PIC16HV753T-I/SL Übersicht
A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory (Flash/ROM), data memory (RAM), and a rich set of peripherals such as timers, ADC, comparators, and communication interfaces. The PIC16 HV family specifically targets applications where the MCU can derive its own low-voltage supply directly from a high-voltage DC bus (such as 12V or 15V) using only an external series resistor and a small decoupling capacitor. Within the broader taxonomy, the PIC16HV753 sits inside the 8-bit PIC16 architecture, itself a member of Microchip's mid-range PIC microcontroller family, used widely in cost-sensitive embedded control.
Key features include a 20 MHz internal oscillator, 12-bit ADC with internal voltage reference, two operational amplifiers/comparators, a 9-bit DAC, enhanced PWM module, and zero-crossing detection. The device integrates a 5.1V shunt regulator that allows direct connection to 12V battery rails typical in automotive and industrial control without an external LDO, simplifying BOM and reducing board area.
The PIC16HV753 uses a Harvard RISC architecture with a 14-bit instruction word, single-cycle execution except for branches, and a hardware stack of 16 levels. Its nanopower technology offers ultra-low sleep currents, making it well suited for battery-backed or energy-harvesting designs that spend long periods in standby and wake periodically.
Typical applications include LED lighting controllers, battery management, smart shunt regulators, 12V automotive body modules, AC line voltage monitoring, capacitive touch front-ends, and compact DC-DC converter control. The wide Vin range plus analog-rich peripherals make it especially attractive for analog-loop control loops where most competing MCUs need external ADCs.
When designing with this part, observe the absolute maximum VDD of 5.5V on the regulated rail; the HV front end can accept higher voltages but the shunt regulator must dissipate the excess power. Always size the external series resistor to limit shunt current below the package's thermal limits during worst-case line conditions. This page synthesizes distributor pricing, drop-in alternatives, and design notes that complement the Microchip datasheet for faster BOM and sourcing decisions.

Typische Anwendungen
PIC16HV753T-I/SL ist geeignet für 7 Anwendungs: LED Lighting Controllers, Automotive 12V Body Electronics, Smart Battery Management, Industrial Sensor Signal Conditioning, AC Line Zero-Cross Detection, Capacitive Touch Front-Ends, Compact DC-DC Converter Control.
LED Lighting Controllers
The PIC16HV753T-I/SL is well matched to constant-current LED drivers because its on-chip 12-bit ADC monitors photodiode or shunt feedback while two comparators and the ECCP PWM module drive MOSFET gate signals at frequencies up to 20 MHz instruction rate. The HV variant's integrated 5.1 V shunt regulator derives the MCU supply directly from a 12 V or 24 V LED string rail through a single series resistor, eliminating an external LDO and shrinking BOM. Nanopower sleep mode reduces standby current for always-on lighting fixtures that must meet energy-star idle budgets. Recommended companion parts include the MCP1700 LDO for auxiliary rails and DMG3415U MOSFETs as switching elements.

Automotive 12V Body Electronics
In automotive body modules such as window lifters, mirror controllers, and seat adjusters, the PIC16HV753T-I/SL's HV input tolerates direct 12 V battery transients up to 15 V without external protection circuitry, simplifying the input filter. Its 12-bit ADC samples position feedback from potentiometers or Hall sensors, while the ECCP PWM drives brushed DC motor bridges. Industrial temperature grade (-40C to +85C) suits cabin and under-hood-adjacent environments. Drop-in compatibility with the 14-pin SOIC footprint lets designers maintain a single PCB layout across product variants. Pair with a TVS diode like SMAJ16A on the HV input for transient protection beyond the on-chip shunt.
Empfohlen
Smart Battery Management
The PIC16HV753T-I/SL serves as a low-cost battery monitor for Li-ion packs, NiMH backup batteries, and supercapacitor banks where its on-chip 12-bit ADC and internal voltage reference provide accurate cell-voltage telemetry without external references. The HV shunt regulator accepts multi-cell stacks up to 15 V through a current-limiting resistor, removing the need for a pre-regulator. Nanopower sleep currents below 1 uA extend shelf life on shipped-but-not-yet-installed packs, while the integrated 9-bit DAC supports programmable charge-current setpoints. The same SOIC-14 footprint simplifies migration between PIC16HV753 and higher-memory parts as product families expand.
Empfohlen
Industrial Sensor Signal Conditioning
For 4-20 mA loop-powered transmitters and bridge sensor interfaces, the PIC16HV753T-I/SL provides two on-chip op-amps that condition the bridge output before the 12-bit ADC, eliminating a separate analog front-end IC. The HV shunt regulator derives the 5 V MCU rail directly from the loop's 12-24 V supply, making it ideal for two-wire sensor heads where quiescent current is critical. The 20 MHz instruction rate runs compensation and linearization algorithms in real time at typical 10 ms loop update intervals. Industrial temperature grade plus internal voltage reference accuracy of +/-2% support calibrated transducer designs.
Empfohlen
AC Line Zero-Cross Detection
The PIC16HV753T-I/SL features a dedicated zero-cross detection module that interfaces directly to the AC mains through a single series resistor, generating an interrupt on each line cycle for triac-based dimmers, solid-state relays, and motor phase-angle drives. Its on-chip comparators and op-amps can amplify small sense signals without external active components. The HV shunt regulator operates from rectified 12 V or 15 V rails typical of offline auxiliary supplies, again removing the external LDO. Combined with nanopower standby, this part targets appliance and smart-switch designs that must meet <100 mW standby budgets.
Empfohlen
Capacitive Touch Front-Ends
Capacitive touch buttons, sliders, and proximity sensors benefit from the PIC16HV753T-I/SL's on-chip comparators and the mTouch peripheral library, which Microchip provides free of charge. The 12-bit ADC supports high-resolution proximity sensing, while the 9-bit DAC provides programmable charge-current references for self-calibration. The HV shunt regulator lets the touch MCU share a 12 V or 24 V industrial supply with the rest of the system without needing a separate 5 V rail. SOIC-14 packaging supports reflow-soldered front-panel PCB assemblies. Pair with the PIC10F200 for low-cost follower MCUs.
Empfohlen
Compact DC-DC Converter Control
The PIC16HV753T-I/SL functions as a digital controller for non-isolated buck, boost, and SEPIC converters up to 15 V input, where the integrated 12-bit ADC samples output voltage and current while the ECCP PWM drives the synchronous MOSFETs. The on-chip op-amp can implement type-III compensation, removing an external op-amp and reducing total BOM cost. Software configurable switching frequencies from 20 kHz to 1 MHz at 20 MHz instruction rate accommodate a wide range of inductor and capacitor selections. The HV shunt regulator accepts input transients and steady-state rails up to 15 V.

Wichtigste Unterscheidungsmerkmale
- Integrated HV shunt regulator eliminates external LDO (vs. PIC16F753-I/SL)
- Higher memory for richer firmware (vs. PIC16HV610-I/SL)
- Better ADC and op-amp integration for analog loops (vs. PIC16F1825-I/SL)
Designhinweise
The integrated HV shunt regulator accepts up to 15 V on the HVIN/VDD pin and regulates to 5.1 V via an internal shunt transistor. Size the external series resistor to limit worst-case shunt current to about 50 mA (typical datasheet maximum). For a 12 V supply and 5 mA MCU load, choose R_series = (Vin - Vreg)/I_total = (12 - 5.1)/(0.055) ~ 125 ohm, 1/4 W. Always include a 1 uF decoupling capacitor on VDD close to the pin and a 0.1 uF HF bypass.
Power dissipation in the shunt regulator is P_shunt = (Vin - 5.1) * I_shunt. Estimated: at Vin=15 V and 50 mA shunt, P = 9.9 V * 0.05 A = 0.495 W. The SOIC-14 package has theta_JA around 70 C/W, giving a junction temperature rise of ~35°C above ambient at 0.5 W, well within the 150°C absolute maximum. Provide a copper pour under the exposed paddle area (the SOIC-14 has none, so use the GND pin copper) to spread heat if shunt current exceeds 30 mA continuously.
Route the HV input trace away from sensitive analog inputs (AN0-AN13) to minimize noise coupling into the 12-bit ADC. Use a star-ground topology with the PIC16HV753 ground pin as the central reference. Place the HVIN series resistor and VDD decoupling capacitors within 5 mm of the IC. Keep analog input traces short and guarded with ground pours on both sides for high-impedance sensor interfaces.
Do not exceed 15 V on the HVIN pin - the absolute maximum is rated for brief transients beyond this with external TVS clamping. The PIC16HV753T-I/SL is not pin-compatible with PIC16HV616T-I/ST which uses a TSSOP-14 footprint, not SOIC-14. When migrating firmware from PIC16HV753 to PIC16F1825, verify register maps because the enhanced mid-range core has different peripheral control bit locations.
Compliance-Informationen
RoHS compliant per Microchip product page. Industrial temperature grade only; AEC-Q100 automotive variants are NOT offered in the HV753 family - use PIC16F753-E/SL extended parts for -40C to +125C operation.
