PCA9421 - PMIC 2 Buck + 2 LDO I2C, Li-ion | NXP
The NXP PCA9421 is a highly integrated power management IC (PMIC) providing two step-down (buck) DC-DC converters with I2C-programmable output voltages plus two LDO regulators, designed for 5V input operation in low-power microcontroller applications, and available in an HVQFN24 (BS) package and a WLCSP25 (UK) package. A PMIC (Power Management IC) is a specialized voltage regulator and power management device that integrates multiple power conversion stages - typically buck converters, LDOs, load switches, and supervision functions - into a single semiconductor. In the power management hierarchy, a PMIC sits above individual DC-DC converters and linear regulators, replacing several discrete power management ICs with one programmable solution, reducing board area, bill-of-materials count, and overall system cost. Key features of the PCA9421 include its dual buck converter architecture with I2C-programmable output voltages, two integrated LDO regulators for low-noise analog or digital rails, and operation from a 5V adapter or regulated supply as indicated by distributor listings. This level of integration makes the part a full power management solution rather than a single-rail regulator, which is its principal differentiator against discrete buck-plus-LDO combinations. Technically, the PCA9421 belongs to the NXP PCA9420/PCA9421 PMIC family, which NXP targets specifically at low-power microcontroller applications and similar systems powered by Li-ion battery and/or a 5V adapter in non-portable applications. The I2C interface allows a host microcontroller to adjust buck output voltages dynamically, supporting dynamic voltage scaling and power-mode sequencing in embedded designs. The two package options - HVQFN24 (BS suffix) and WLCSP25 (UK suffix) - give designers a choice between a hand-inspectable QFN footprint and an ultra-compact wafer-level chip-scale package for space-constrained boards. Typical applications include low-power microcontroller power supplies, battery-powered IoT sensor nodes, portable and non-portable devices powered by Li-ion cells or 5V adapters, and general embedded systems requiring multiple sequenced voltage rails from a single input. When designing with the PCA9421, consult the NXP datasheet for the exact buck and LDO current limits, programmable output voltage ranges, and I2C register map, and verify thermal performance for the chosen package option before finalizing the PCB layout. This page synthesizes distributor pricing context, same-family drop-in alternatives, application guidance, and design notes that go beyond the information available on the manufacturer datasheet alone, providing engineers with a consolidated selection resource.

In the power management hierarchy, the PMIC sits between the system power source (battery or adapter) and the load devices (MCU core, I/O, memory, analog rails), replacing several discrete regulators and reducing board area, BOM count, and design complexity. The PCA9421BSZ integrates two high-efficiency buck converters and two low-noise LDOs with programmable output voltage ranges, enabling dynamic voltage scaling for low-power MCU cores. The device supports a 5 V input and is optimized for i.MX RT power domains, providing the core, I/O, and analog rails required by these processors. Its I2C-compatible control interface allows runtime voltage adjustment and power state management, which is essential for battery-powered systems that must balance performance against power consumption. Typical applications include i.MX RT-based industrial controllers, portable medical devices, battery-powered IoT edge nodes, and handheld instrumentation. The integrated bucks deliver high efficiency at moderate load currents, while the LDOs supply noise-sensitive analog and I/O rails. The compact HVQFN-32 package with exposed pad supports thermal dissipation in space-constrained designs. When designing with the PCA9421BSZ, pay close attention to inductor selection for the buck converters, input and output capacitor placement, and the thermal pad soldering to the PCB ground plane. The programmable output voltages must be configured through the I2C interface during initialization, so firmware sequencing must match the MCU power-up requirements.

High integration makes it a natural companion for NXP i.MX RT crossover MCUs and other low-power microcontroller systems. Architecturally, the PCA9420/PCA9421 family shares a common platform: the bucks provide the main processor core and I/O rails, while the LDOs supply analog, PLL, or real-time-clock domains. I2C control enables runtime configuration of rail voltages, enable states, and sequencing, which is essential for multi-rail processors that require specific power-up and power-down order. Typical applications include battery-powered IoT sensor nodes, wearable devices, portable medical accessories, and industrial wireless endpoints built around i.MX RT or similar low-power MCUs. The dual-input (battery/5 V adapter) topology also suits smart-home devices and USB-adapter-powered accessories. When designing with the PCA9421, verify buck inductor selection and LDO headroom against the actual load currents in the manufacturer datasheet, and implement the recommended I2C configuration early in firmware bring-up since rail voltages default to programmable states rather than hard-wired dividers.

The high level of integration makes it suited to small-battery products where every square millimeter and every microamp of standby current matters. Architecturally, the PCA9422 was designed in close conjunction with the i.MX RT500/RT600/RT700 power architecture, so its regulated rails and charge profile match the sequencing and brown-out requirements of those MCUs without external sequencing logic. The WLCSP packaging minimizes loop inductance and footprint, and on-chip charging control removes the need for a separate charger IC in wearables and hearables. Typical applications include battery-powered wearables, hearables and smart-sensor nodes built around the i.MX RT500/RT600/RT700, and other small-battery microcontroller systems that need charging plus power distribution in one device. When designing with this device, verify the charge current setting against your battery cell's 1C rating and confirm thermal dissipation of the linear charger at maximum VIN-to-VBAT differential - linear charging at 640 mA can dissipate significant power if the input rail is much higher than the battery voltage.

Architecturally, the device integrates the charger state machine, battery gauge functionality and configuration registers behind a standard I2C serial interface, allowing the host microcontroller to monitor charge status and battery parameters while the PMIC autonomously manages the charge cycle. This offloads power management from the MCU firmware and improves overall system robustness. Typical applications include battery-powered IoT sensor nodes, wearable devices, portable medical accessories, and low-power microcontroller systems such as NXP i.MX RT-class edge platforms with small batteries, where a complete single-chip power solution minimizes solution size. Design consideration: because the linear charger dissipates (VIN - VBAT) x ICHG as heat, limit charge current or input voltage differential in thermally constrained enclosures, and use the JEITA temperature monitoring with an appropriate NTC to protect the cell.

In the power-management hierarchy, the PMIC sits above individual voltage regulators and below the system controller, offering sequenced power-up, I2C-bus programmability, and protection functions tailored to a specific processor family such as the NXP i.MX application processors. Key differentiating features include three buck converters that support dynamic voltage scaling (DVS) for the i.MX 93 core rails, allowing the software to trade processor frequency against power consumption; a 400 mA integrated load switch for peripheral power domains; and interrupt-driven supervision via the IRQ_B pin, which asserts LOW on any unmasked interrupt status change and releases HIGH after the application processor reads the INT1 register. The PCA9452 communicates over an I2C-bus interface supporting Standard-mode (100 kbit/s), Fast-mode (400 kbit/s), and Fast-mode plus (1 Mbit/s) transfers. The I2C address at Power-On Reset is defined in Table 17 of the manufacturer datasheet, enabling multi-PMIC systems without address conflicts. The oscillator driver section supports an external 32.768 kHz crystal for the processor's real-time clock domain, and the 2-channel level translator bridges rail domains of different voltages in the i.MX 93 power tree. Typical applications include automotive infotainment and cluster displays based on the i.MX 93, extended-industrial HMI panels, edge-AI gateways, and battery-backed telematics units, all of which need precisely sequenced, low-quiescent-power rails. The single-chip approach reduces board area, BOM count, and total power-tree design risk compared with discrete regulator stacks. A key design consideration is buck inductor selection and layout: the DVS-capable bucks change their target output voltage under software control, so compensation and output capacitance must be chosen per the manufacturer datasheet reference design to keep transient response within processor specification during frequency transitions.

An LED driver IC is a specialized power-management semiconductor that translates low-level digital commands (typically I2C) into per-channel current sinks or sources for solid-state lighting. LED drivers sit within the broader hierarchy of display and lighting ICs, bridging microcontrollers and high-brightness LED arrays, and are commonly used in laptops, monitors, and architectural lighting. The PCA9532 family specifically targets I2C-controlled PWM dimming with hardware-software frequency selection and two programmable blink rates. Key features include 16 individually programmable outputs, a built-in 256-step PWM that can be assigned to any output in two banks, software and hardware selectable I2C addresses (up to 8 devices on one bus), a 400 kHz Fast-mode I2C interface, an internal oscillator with two user-programmable blink rates, and 25 mA continuous per-channel sink current. Each output can be independently set to ON, OFF, blink at a programmed rate, or PWM-dimmed to one of 256 brightness levels. Internally, the PCA9532BS combines a CMOS I2C slave with logic decoders, two 8-bit PWM frequency registers, two 8-bit PWM registers that the device multiplies to 256 steps, and 16 open-drain MOSFET drivers. The 256-step PWM is created internally rather than counted out by the host, freeing the MCU for other work and ensuring consistent dimming across all channels regardless of bus traffic. Typical applications include RGB LED color mixing for ambient lighting, LED backlight control in LCD panels and notebooks, status indicators and signage, keypad backlights, and any compact electronic product that needs software-controllable individual LED brightness. Two PCA9532 devices can be configured to drive 32 LEDs in a stereo audio bar-graph or 24 LEDs plus a keypad scanner in a handheld instrument. When designing with the PCA9532BS, place a 0.1 uF bypass capacitor close to VDD, use a 1.5 kohm pull-up on SDA/SCL for reliable 400 kHz operation, and ensure the LED supply (typically 3.3 V or 5 V) stays within the absolute maximum ratings. Output current should be limited by a series resistor; do not exceed 25 mA continuous per pin or the device will enter thermal shutdown.

PCA9632DP2Z - 4-bit 25mA I2C LED Driver | NXP Semiconductors
The NXP Semiconductors PCA9632DP2Z is an I2C-bus controlled 4-bit LED driver optimized for Red/Green/Blue/Amber (RGBA) color mixing applications, housed in a 10-pin TSSOP package. It provides 4 outputs with 25 mA per channel and operates as a drop-in upgrade for the PCA9633 with 40x power reduction. The device uses NXP's Fm+ (Fast-mode Plus) I2C interface capable of 1 MHz bus speeds for high-throughput color control. An LED driver is an integrated circuit that regulates current and brightness for light-emitting diodes, eliminating the need for discrete current-limiting resistors and enabling software-controlled dimming. LED drivers occupy the lighting subsystem tier of an embedded product, sitting below the microcontroller (which commands colors and animation sequences) and above the physical LEDs. Within the LED-driver category, the PCA9632 belongs to the I2C-controlled constant-current driver sub-class, a category that includes both 8-bit PWM (e.g., PCA9685) and 4-bit group-brightness devices like this one. Choosing the right driver involves balancing bit depth (color resolution), per-channel current, bus speed, and standby power for the target application. Key features include 4 individually controlled outputs, software-programmable group dimming (4-bit), individual LED brightness control, a 1 MHz Fm+ I2C interface, and ultra-low standby current. Each output delivers up to 25 mA and supports per-output programmable on/off and group dimming. The device integrates power-on reset, software reset, and four hardware-selectable I2C addresses via two ADDR pins, allowing up to 16 PCA9632 devices on a single bus for 64-channel systems. Internally, the PCA9632 uses a current-switch architecture with 4-bit PWM for group dimming and 8-bit PWM per channel for individual brightness. The integrated constant-current sinks eliminate the need for external current-limiting resistors, simplifying PCB layout and improving channel-to-channel matching. The Fm+ I2C interface supports standard (100 kHz), fast (400 kHz), and fast-mode plus (1 MHz) bus speeds. Typical applications include RGBA backlight control for handheld devices, RGB status indicators, decorative lighting, gaming peripherals, and IoT nodes with addressable color feedback. The 4-bit group dimming combined with 8-bit per-channel PWM produces 16 million effective colors (4,096 group steps x 256 channel steps). When designing with this part, ensure the LED forward voltage plus headroom remains below VDD. Decouple VDD with a 100 nF ceramic capacitor close to the IC and follow I2C bus layout best practices for the 1 MHz Fm+ speed grade.

PCA9633TK,118 - 4-bit 25mA I2C LED Driver HVSON8 | NXP
The NXP PCA9633TK,118 is a 4-bit 25 mA I2C-bus controlled LED driver optimized for Red/Green/Blue/Amber (RGBA) color mixing applications, housed in an 8-pin HVSON (3x3 mm) package. Each of the four LED outputs provides 8-bit resolution (256 steps) of fixed frequency PWM brightness control, and the device supports a 1 MHz Fast-Mode Plus (Fm+) I2C interface for high-speed host communication. A LED driver (Light-Emitting Diode driver) is an active electronic circuit that regulates current or voltage through one or more LEDs to set brightness, color mixing, and on/off timing. Within the broader power-management hierarchy, the PCA9633 sits under constant-current LED drivers -> LED drivers -> power management ICs -> semiconductors. The PCA9633TK variant uses voltage-switch (open-drain) outputs, making it well suited to driving low-voltage LEDs or external MOSFET-controlled higher-current strings while the host MCU retains color-mixing intelligence. Key differentiating features include per-output 8-bit PWM at 97.6 kHz nominal frequency to eliminate audible flicker in RGBA mixing, software-programmable output state inversion, group PWM/blink control, and a hardware-reset input with power-on reset. The wide 2.3 V-5.5 V supply range supports both 3.3 V and 5 V logic rails commonly found in RGB backlights and indicator panels. Architecturally the part uses an I2C slave state machine, a 4 MHz internal oscillator (divided down for PWM), and four open-drain output drivers rated at 25 mA continuous each. Outputs can be paralleled for higher current without external logic changes, and the device supports up to 126 selectable I2C addresses in the 16-pin version, enabling large addressable LED arrays. Typical applications include RGBA color-mixing for signage and architectural lighting, RGB keypad backlighting in consumer electronics, status indicators on networking hardware, and LED-blinking alert patterns on industrial HMIs. Designers choose this part when they need fine-grained PWM control of four low-current LEDs without an external driver FET. When designing, confirm that each LED's forward voltage does not exceed the open-drain pull-up tolerance and select a current-limit resistor (or constant-current driver) sized for the chosen LED bin. Decouple VDD with a 100 nF ceramic capacitor placed within 2 mm of the supply pin to suppress switching transients during PWM transitions.

PCA9685PW - 16-Channel 12-bit PWM I2C LED Controller | NXP TSSOP-28
The NXP Semiconductors PCA9685PW is a 16-channel, 12-bit PWM Fm+ I2C-bus LED controller housed in a 28-pin TSSOP (SOT361-1) package, optimized for Red/Green/Blue/Amber (RGBA) color backlighting. Each of the 16 LED outputs has its own 12-bit resolution (4096 steps) fixed-frequency PWM controller that operates at a programmable frequency from typically 24 Hz to 1526 Hz, with a duty cycle adjustable from 0% to 100% for fine-grained brightness control. The device is rated for 25 mA sink current per output and operates from a 1 MHz Fast-Mode Plus I2C interface, allowing up to 62 devices to share a single bus via six hardware address pins. An LED driver is an integrated circuit that switches current through light-emitting diodes at controlled duty cycles and frequencies, allowing microcontrollers to drive many more LEDs than their limited GPIO pins can support directly. The PCA9685 belongs to the LED driver / PWM controller product family within the display driver hierarchy, which sits inside power management and lighting sub-systems. Compared to discrete MOSFETs driven by GPIO bit-banging, a dedicated LED controller IC delivers programmable frequency, smooth 12-bit dimming, hardware current sinking, and synchronized multi-channel phase shifting - critical for avoiding audible flicker and for removing the MCU's software timing burden. Key features include six hardware-selectable I2C addresses, a 1 MHz Fm+ capable SCL clock, programmable open-drain totem-pole output structure with 25 mA continuous sink, per-output 12-bit duty cycle plus 4-bit group Blink/Blink-at-fixed-frequency mode, and a 40 mA active-low Output Enable (OE) input for synchronized dimming via external PWM. The internal 25 MHz oscillator provides the time base and supports the wide 24 Hz - 1526 Hz PWM range with sub-percent duty cycle resolution. The PCA9685PW architecture combines an I2C slave decoder, a frequency prescaler, and 16 independent 12-bit PWM latches, all driven by a single on-chip 25 MHz RC oscillator. Outputs can be configured as totem-pole (push-pull) or open-drain, providing flexibility to drive both LED cathodes to GND and LED anodes to V+. The OE pin enables global phase-shifted PWM dimming - critical when multiple PCA9685PW ICs must be synchronized to a common refresh rate for large LED matrices. Typical applications include LCD TV/monitor RGBA LED backlighting, RGB LED strip driving, servo motor control via PWM (hobby robotics), LED matrix displays, and PC case lighting. Designers choose the PCA9685PW when they need more than the 4-6 PWM channels a typical MCU offers, require 12-bit dimming depth, or must chain multiple drivers on one I2C bus. When designing with this device, place the 220 nF bypass capacitor on VDD and the 1 uF + 2.2 uF bulk capacitors on V+ as close as possible to the pins, and keep the SDA/SCL traces short. The OE pin must be tied HIGH when not used; leaving it floating can cause undefined output behavior.

PD-3501G/AC-US - 15.4W Gigabit PoE Midspan Injector | Microchip
The Microchip Technology PD-3501G/AC-US is a single-port Gigabit Power over Ethernet (PoE) midspan injector that converts AC mains power into 48V DC PoE output at up to 15.4W, compliant with IEEE 802.3af, with 10/100/1000 Mbps data-rate pass-through and a US power cord. A PoE midspan injector (also called a PoE adapter or power injector) is a network device that adds DC power to an existing Ethernet data cable without altering the switches or cabling already installed. It sits in-line between a non-PoE network switch and a powered device (PD) such as an IP camera, injecting power on the spare pairs or center taps per the IEEE 802.3af standard. Within the power-over-Ethernet hierarchy, it belongs to the midspan (endpoint-independent) class of power sourcing equipment (PSE), as opposed to an endspan PoE switch. Key features of the PD-3501G include full IEEE 802.3af compliance guaranteeing safe detection and classification of powered devices, Gigabit Ethernet pass-through so 1000BASE-T data rates are preserved, and plug-and-play installation that leaves the existing network infrastructure completely unaltered. The unit delivers a nominal 48V DC output at up to 0.32A (15.4W) from an AC mains input of up to 240V via an IEC 320-C14 inlet. Technically, the midspan performs the PSE functions required by 802.3af: it applies a detection signature to identify a valid PD, optionally reads the classification signature, and only then applies the 48V power, protecting legacy non-PoE equipment from damage. Detection also enables hot-plugging of terminals without disrupting data traffic. Typical applications include powering IP phones, WLAN access points, and network cameras in offices, campuses, and low-port-density installations where upgrading to a PoE switch is unnecessary or uneconomical. For design-in and deployment, remember that the total cable run, including the midspan, must stay within the 100 m Ethernet channel limit, and the powered device must be 802.3af Class 0 through Class 4 compatible to fit within the 15.4W budget. This page adds unique value beyond the manufacturer datasheet: it synthesizes distributor pricing tiers, drop-in cord-code and family alternatives, deployment design notes, and AEO-optimized FAQs in one place.
PD-9001GM - 30W Single-Port Gigabit PoE Midspan | Microchip
The Microchip Technology PD-9001GM (PowerDsine 9001G family) is a single-port Power over Ethernet (PoE) midspan injector that delivers up to 30 Watts over Gigabit Ethernet cabling, compliant with the IEEE 802.3at PoE+ standard and backward compatible with IEEE 802.3af, packaged as a compact standalone desktop/wall-mountable unit. A PoE midspan, also called a PoE injector or power injector, is a device that adds electrical power to a standard Ethernet data line without replacing the network switch. Positioned between a non-PoE switch and a powered device (PD), it injects DC power onto the spare or data pairs of the Cat5e/Cat6 cable while passing 10/100/1000 Mbps data traffic transparently. Midspans sit in the power-delivery layer of the network hierarchy: Ethernet infrastructure -> PoE power sourcing equipment (PSE) -> powered devices such as access points and cameras. Key features include 30W power output per port for high-power applications, full Gigabit (10/100/1000 Mbps) data-rate pass-through, IEEE 802.3at compliance with 802.3af backward compatibility, and automatic detection and classification of powered devices. The unit powers up the PD only when a valid 802.3af/at signature is detected, protecting non-PoE network equipment from damage. The midspan integrates the PSE controller and a flyback power supply in one enclosure, generating the 50-57V PoE output rail from a mains AC input, with short-circuit, over-current and over-temperature protection per the IEEE standard. This avoids the cost and downtime of replacing an existing non-PoE Ethernet switch when only one or a few ports need power. Typical applications include powering WLAN 802.11n/ac access points, IP network cameras including PTZ models, VoIP video phones and other IP terminals in enterprise, retail and surveillance installations where only one port requires PoE. Design and deployment consideration: verify that the connected cabling is Cat5e or better and that the powered device's power class does not exceed the 30W budget; a midspan cannot combine power with a PoE switch port on the same link. This page synthesizes verified manufacturer and distributor data, family cross-references, and deployment guidance not found on a single datasheet.
PD-9001GM/AC - 30W PoE Midspan Injector, Gigabit | Microchip
The Microchip Technology (formerly Microsemi / PowerDsine) PD-9001GM/AC is a single-port, high-power Power-over-Ethernet (PoE) midspan injector that delivers up to 30 W of DC power over standard Ethernet cabling while passing 10/100/1000Base-T data traffic transparently. The unit accepts a universal AC mains input (via the integrated AC variant cord-set) and injects IEEE 802.3at Type 2 (PoE+, 30 W) onto a Gigabit Ethernet pair-set, with full backward compatibility to IEEE 802.3af (15.4 W) powered devices. PD-9001GM/AC operates without affecting the data path, making it ideal as a drop-in upgrade for networks that need to power newer high-draw endpoints without replacing existing switches. A PoE midspan (also called a PoE injector or "power inserter") is a layer-1 power-sourcing device placed in-line between a non-PoE Ethernet switch and a powered terminal (PT). It negotiates the signature, classification, and power-allocation handshake over the spare or signal pairs defined in IEEE 802.3, then supplies 48-57 V DC up to the negotiated class. Midspans belong to the broader PoE power-sourcing-equipment (PSE) hierarchy, alongside PoE-capable switches and end-span injectors; they are typically used when retrofitting legacy switches to support new high-power Wi-Fi 6/6E APs, PTZ cameras, or VoIP phones. Key features of the PD-9001GM/AC include gigabit (10/100/1000Base-T) pass-through, surge protection on the data port, support for both 802.3at (2-event) and 802.3af classification, and a guaranteed 30 W output at the PD. The chassis ships with indicator LEDs (AC power, channel power), an IEC C5/C7 AC inlet (cord-set variant), and integrated thermal management for fanless operation. The midspan is targeted at small-office / branch-office networks where silent operation, compact form factor, and standards-compliant negotiation matter more than rack-density. From a design viewpoint, the PD-9001GM/AC provides a complete, externally-powered PSE solution - no host-side firmware or driver stack is required. Because the device is a sealed plug-top / desktop midspan, engineers can treat it as a black-box AC-to-PoE converter in their system BOM rather than designing discrete PoE PSE hardware. This simplifies compliance, EMI, and thermal design while supporting mixed-vintage 802.3af and 802.3at loads on the same infrastructure. Typical applications include powering 802.11ac / 802.11ax Wi-Fi access points, pan-tilt-zoom (PTZ) surveillance cameras, IP video phones, thin-client terminals, and small-cell or IoT gateways. Because the unit is gigabit-rated, it supports modern high-throughput APs that the older 100 Mb-only 9001G cannot power without bottlenecking the uplink. For deployment, mount the midspan on a flat surface within 100 m cable reach of the powered device, connect the "Data In" RJ-45 to the existing switch, and "Data & Power Out" to the PD; ensure the AC inlet is on a properly grounded outlet. No software configuration is required - classification, inrush, and disconnect detection are handled internally per IEEE 802.3at.

PD-9506GC - 6-Port 60W BT PoE Midspan | Microchip Technology
The Microchip Technology PD-9506GC is a 6-port, 60 W per-port indoor Power-over-Ethernet (PoE) midspan injector that is fully compliant with the IEEE 802.3bt standard. Designed for high-power Powered Devices (PDs), it delivers up to 60 W on each of six Gigabit Ethernet (10/100/1000 Mbps) data pass-through ports, supporting emerging high-wattage applications such as IEEE 802.11ax Wi-Fi 6 access points, PTZ and dome network cameras, IP videophones, thin clients, and color-touch displays. A PoE midspan is a network appliance that sits between a non-PoE Ethernet switch and PoE-powered end terminals, injecting DC power onto the spare or data pairs of standard TIA/EIA-568 cabling without requiring replacement of the existing switch. Within the broader power-management taxonomy, the PD-9506GC belongs to the Power Sourcing Equipment (PSE) category of midspans, which itself sits above simple PoE splitters and below full PoE-enabled switches in Ethernet-power deployment hierarchies. Key features include support for all four 802.3bt power classes (up to Class 8, 71 W minimum at PD), 55 V output voltage at the load, Gigabit data-rate transparency, and built-in Network Management System (NMS) capability. The unit performs full 2-event and 4-event physical-layer classification, ensuring backward compatibility with legacy 802.3af (15.4 W) and 802.3at (30 W) PDs while enabling new high-power installations. Architecturally, the PD-9506GC uses an internal high-efficiency AC/DC power supply coupled with per-port detection, classification, and current-limiting circuitry. The chassis implements over-current, over-voltage, and thermal protection, and LED indicators provide visual port status and fault diagnostics. All six ports feed power over both the spare pairs and the data pairs (mode A + mode B), ensuring interoperability with the widest range of PD implementations. Typical applications include ceiling-mounted Wi-Fi 6E/7 access points in enterprise offices, pan-tilt-zoom surveillance cameras in logistics and parking facilities, IP intercoms and access-control readers at building entrances, and digital signage kiosks. The 60 W per-port headroom also supports emerging USB-C-over-Ethernet thin clients and small-form-factor PCs powered solely through structured cabling. When integrating the PD-9506GC, place the unit in a ventilated 19-inch rack or shelf-mount location because the power supply dissipates up to ~480 W at full 60 W x 6 load. Use only Cat5e or higher cabling, and budget an additional ~0.5 A per port for inrush spikes during PD classification. Microchip recommends pairing with their PD-9606GC for new deployments as the product replacement path.

PD-9606GC - 6-Port 90W IEEE 802.3bt PoE Midspan | Microchip
The Microchip Technology PD-9606GC is a 6-port Power over Ethernet (PoE) midspan injector that delivers up to 90 W per port and is fully compliant with the IEEE 802.3bt Type 4 standard while remaining backward compatible with IEEE 802.3af/at. It is housed in a 1U-style rack-mountable indoor enclosure with six RJ-45 data inputs, six RJ-45 data+power outputs, and an AC power inlet, and supports 10/100/1000 Mbps (Gigabit) Ethernet pass-through. Each port negotiates power with the connected Powered Device (PD) using the 802.3bt Type-3/Type-4 handshake and supplies up to 90 W at 54 V nominal output. A Power over Ethernet midspan (also called a PoE injector) is a device that sits between a non-PoE Ethernet switch and end terminals, injecting DC power onto the twisted-pair cabling so that the switch itself does not need PoE capability. The PD-9606GC belongs to the broader midspan family of PoE midspans -> PoE injectors -> PoE power sourcing equipment -> industrial power supplies -> power conversion products. Midspans are used in installations where the existing Ethernet switch is fixed and PoE functionality must be added without replacing it. Key features of the PD-9606GC include per-port power output of up to 90 W (Type 4), full backward compatibility with 802.3af (15.4 W) and 802.3at (30 W), plug-and-play installation with no configuration required for basic operation, and Microchip's PowerView Pro secure remote management via SNMPv3 over IPv4 or IPv6. Built-in protections include detection, classification, overload, and short-circuit protection per the 802.3bt specification, as well as per-port current limiting. The internal architecture combines a universal-input AC-to-DC front end that produces a 54 V bulk rail with six independent PoE controller channels. Each channel performs the IEEE 802.3bt handshake, classifies the attached PD, and applies the 54 V rail through current-sense and MOSFET switching. Gigabit data pairs are passed through untouched on the data pairs, while power is injected on the spare pairs (Mode A) or both data and spare pairs (Mode B) as required by the negotiated class. Typical applications include powering IEEE 802.11ax/802.11ac Wi-Fi 6 access points, PTZ and dome IP cameras, IP videophones, thin clients, digital signage displays, point-of-sale terminals, and small-cell or picocell radio units. Any 802.3bt-compliant high-power end device can be powered without needing a local AC outlet at the endpoint. When deploying the PD-9606GC, verify that the upstream Ethernet switch supports pass-through data only (the midspan handles all PoE logic), confirm that cabling is rated Category 5e or better, and budget for chassis airflow because the unit dissipates heat proportional to total delivered power (up to 540 W at full 6-port 90 W load).

The Microchip Technology (Microsemi / PowerDsine) PD-9606GC/AC is a 6-port IEEE 802.3bt-compliant Power over Ethernet midspan injector delivering up to 90 W per port at 55 V DC (1.64 A per port) with 10/100/1000 Mbps data rates over Cat 5/5e/6 cabling. A PoE midspan injector is a network device that adds power to an Ethernet link without replacing the existing Ethernet switch. It sits between the switch and the powered device (PD), injecting DC power onto the cable pairs while passing data traffic untouched. In the power-management hierarchy it belongs to the Power over Ethernet equipment family defined by IEEE 802.3af/at/bt standards, complementing endspan (PoE switch) architectures. Key features include 90 W per port under the IEEE 802.3bt (Type 4 / 4PPoE) standard, backward compatibility and safe operation with 802.3af/at powered devices, gigabit-transparent data pass-through, network management capability (NMS variant family), and a six-port form factor in the PowerDsine PD-9600GC family, which also spans 12-port and 24-port models for scalable deployments. The PD-9600GC family powers IEEE 802.11 wireless access points, Pan-Tilt-Zoom (PTZ) and dome IP cameras, IP videophones, thin clients, and other high-power Ethernet end terminals. DC power is supplied over both spare and data pairs of the cable (pairs 1/2, 3/6, 4/5, 7/8) in a 10/100/1000Base-TX network over TIA/EIA-568 category 5/5e/6 cabling, per the PD-96xxGC user guide. Typical applications include enterprise Wi-Fi 6/6E access point deployments that exceed 60 W, surveillance installations with heaters and IR illuminators in PTZ dome cameras, and powering thin clients or digital signage in office and industrial environments. Design consideration: verify total system power budget. A 6-port 90 W unit can demand up to 540 W from the AC mains, so confirm facility provisioning and ventilation clearances in enclosed racks.
