TPS65217CRSLT - Single-Chip PMIC for AM335x | Texas Instruments
MPN: TPS65217CRSLT ✓ نشطTPS65217CRSLT نظرة عامة
A PMIC (Power Management Integrated Circuit) is a highly integrated device that consolidates multiple voltage rails, charging, sequencing, and supervisory functions into a single silicon die. In the system hierarchy, it sits between the input power source (battery or wall adapter) and the application processor, replacing what would otherwise be 5-10 discrete regulators. PMICs are essential in space-constrained portable designs such as tablets, handhelds, and embedded modules where board area, BOM count, and power-sequencing reliability are critical design constraints.
The TPS65217CRSLT supports 2-A output current on the linear charger power path with a 700-mA maximum charge current, 20-V tolerant USB and AC inputs, and an 1800-mA current limit option on the USB input. Thermal regulation, dynamic power-path management, and integrated power-good signaling simplify host-side firmware. The high-frequency 2.25-MHz switching converters enable the use of small 1-uH inductors and 0402/0603 ceramic capacitors, reducing total PCB footprint.
Architecturally, the device combines hysteretic and PWM buck controllers for high efficiency across load, low-Iq LDOs for always-on rails, and a current-mode linear charger with JEITA-style thermal regulation. The integrated boost converter drives white LEDs for display backlighting with software-controllable brightness. According to the TI datasheet PDF, the TPS65217x family is shipped in a 48-pin leadless 6-mm x 6-mm VQFN package with 0.4-mm pitch, and is qualified for industrial temperature ranges.
Typical applications include AM335x-based Sitara processor boards (BeagleBone Black, industrial HMI panels), portable medical data-acquisition tablets, handheld barcode scanners, e-readers, and ruggedized 5-V point-of-sale terminals. The wide 4.3-5.8-V input range makes it directly compatible with USB 2.0/3.0 VBUS rails, single-cell Li-ion batteries, and 5-V regulated adapters without additional front-end conditioning.
When designing with the TPS65217CRSLT, place the input bulk capacitors as close as possible to the PVIN and PGND pins to minimize parasitic inductance. Use a 4-layer PCB with a dedicated ground plane for best thermal performance at 2-A charging current. Refer to the TI TPS65217EVM evaluation module schematic for reference layout, recommended inductor selection, and proper power-good pull-up configuration.

التطبيقات النموذجية
TPS65217CRSLT مناسب لـ 7 التطبيقs: AM335x Sitara Processor Board, Portable Medical Tablet, Handheld Barcode Scanner, 5-V Line-Powered HMI Panel, Single-Board Computer (BeagleBone-class), Point-of-Sale (POS) Terminal, E-Reader / Low-Power Display Device.
AM335x Sitara Processor Board
The TPS65217CRSLT is the reference PMIC for AM335x ARM Cortex-A8 Sitara designs, providing all required rails from a single 5-V input. The three 2.25-MHz DC/DCs power the core (VDD_MPU at up to 1.2 A), DDR memory, and I/O domain, while the four LDOs supply PLL/auxiliary rails at <1% ripple. Compared to a discrete regulator tree, the TPS65217CRSLT saves approximately 60 percent of PCB area around the SoC and integrates the power-up sequencing logic required by AM335x hardware guidelines.

Portable Medical Tablet
Battery-powered medical tablets built around AM335x use the TPS65217CRSLT to consolidate charging, system rails, and LED backlight drive into one IC. The integrated 2-A linear charger with 20-V tolerant USB input handles hospital-grade 5-V adapters safely, and thermal regulation prevents charge current from exceeding safe skin-temperature limits during continuous bedside use. The boost LED driver powers the LCD backlight at up to 30 mA per string, eliminating a separate backlight IC.

Handheld Barcode Scanner
Industrial handheld scanners benefit from the TPS65217CRSLT's wide 4.3-5.8 V input range, dual-input USB/AC power path, and high-efficiency 2.25-MHz buck converters. The integrated charger supports a single 18650 Li-ion cell or 1S Li-polymer pack up to 2 A discharge, while the four LDOs power the scanner laser, BLE radio, and display. The 6x6-mm VQFN package fits inside scanner handles with 50-mm diameter cross-sections.

5-V Line-Powered HMI Panel
Factory-floor Human-Machine Interface panels use the TPS65217CRSLT to convert a regulated 5-V supply into all AM335x core and I/O voltages with sequenced power-up. The 4 LDOs deliver clean rails to the touchscreen controller, RS-485 transceiver, and CAN PHY without requiring additional filtering. The 2.25-MHz switching frequency keeps EMI below industrial EN 55011 Class A limits when paired with a 4-layer PCB layout.

Single-Board Computer (BeagleBone-class)
Open-source single-board computers built around AM335x - similar to BeagleBone Black - depend on the TPS65217CRSLT as a turnkey PMIC. The integrated power path allows simultaneous charging from USB and operation of the SoC, ideal for developer boards. The exposed thermal pad dissipates charger heat to the PCB copper pour, supporting 2-A continuous charging without external heatsinking.

Point-of-Sale (POS) Terminal
Compact POS terminals use the TPS65217CRSLT to power AM335x-based mainboards, thermal printer drivers, and contactless card readers from a single 5-V wall adapter or USB-PD source. The integrated charger enables battery-backed operation for mobile cart-tap terminals, and the four LDOs supply the 3.3-V, 1.8-V, 1.2-V, and 1.0-V rails without a separate PMIC. Wide 4.3-5.8 V input accommodates voltage drop on long USB-PD cables.

E-Reader / Low-Power Display Device
E-ink readers and low-power signage displays leverage the TPS65217CRSLT's high-efficiency 2.25-MHz buck converters and four low-Iq LDOs to extend battery life during standby. The boost LED driver is repurposed for backlight or frontlight strings in frontlit e-readers, eliminating a discrete boost IC. With AM335x in low-power deep-sleep states, total system quiescent current drops below 100 uA on the TPS65217 rails.

ملاحظات التصميم
At 2-A continuous charge current from a 5-V USB source into a 3.7-V Li-ion cell, the TPS65217CRSLT dissipates up to 2.6 W as heat in the linear charger. The 48-pin VQFN package with exposed thermal pad has a typical theta_JA of approximately 28 C/W on a 4-layer JEDEC board. Use at least 1 square inch of top-layer copper tied to PGND to keep the junction temperature rise below 50 C above ambient. For high-ambient (>60 C) enclosures, derate charge current via ISET1/ISET2 resistors.
Place input bulk capacitors (10 uF X5R minimum) within 3 mm of the PVIN and PGND pins to minimize parasitic inductance that couples switching noise into the analog rails. Route the LX1/LX2/LX3 switch-node traces short and narrow (under 5 mm), and shield each switch node with a grounded copper pour on the layer below. Per the TI TPS65217EVM reference design, use a 4-layer stack-up with layer 2 as a solid ground plane to provide the best EMI and thermal performance.
Tie the AGND and PGND pins to a single-point ground connection at the exposed thermal pad to avoid ground loops between the analog control circuits and the high-current switching returns. Do not route analog signal traces (I2C, ISET, PGOOD, nRESET) parallel to the LX switch nodes for more than 5 mm without a ground shield - coupling can inject noise into the host I2C bus and cause intermittent communication failures during load transients.
Do not exceed the 20-V USB/AC adapter transient rating by hot-plugging inductive adapters without external TVS protection. The internal clamps will dissipate the surge but may exceed absolute maximum ratings on rapid transients above 24 V. Add a USBLC6-2SC6 or equivalent TVS array at the connector if the system is used with automotive or industrial 12-24 V sources. Also verify that the THERM pin thermistor network uses a 10-kohm NTC (beta = 3950) per TI reference schematic - incorrect NTC beta values disable JEITA-style thermal protection.
