Texas Instruments TPS22932BYFPR

Overview

TPS22932BYFPR from Texas Instruments is a single-channel, ultralow r_ON P-channel load switch for low-voltage power rail control, operating from 1.1 V to 3.6 V input, delivering up to 500 mA continuous current with 75 mΩ r_ON at 1.8 V, controlled slew rate (165 μs rise time), and configurable 3-bit logic enabling MUX/AND/OR/NAND/NOR/inverter/noninverter functions in portable power management.

For engineers reviewing the TPS22932BYFPR datasheet, TPS22932BYFPR pinout, TPS22932BYFPR application, or TPS22932BYFPR equivalent, key selection criteria include its 1.1–3.6 V input range, 120 Ω quick-output-discharge resistor, sub-1 μA quiescent/shutdown current, DSBGA-6 package (0.80 mm × 1.20 mm), and compatibility with 1.2-V/1.8-V/2.5-V/3.3-V GPIO control signals.

Technical Context

The TPS22932BYFPR integrates a P-channel MOSFET with internally controlled turn-on slew rate to limit inrush current, and features a configurable 3-bit logic decoder that maps ON1/ON2/ON3 inputs to eight discrete switching states (e.g., ON/OFF, MUX, AND, OR) without external components. Its control threshold supports direct interfacing with low-voltage microcontroller GPIOs across multiple I/O standards.

It includes an on-chip 120 Ω pulldown resistor for rapid output discharge upon disable, preventing floating outputs and reducing system-level leakage. Thermal design is supported by R_θJA = 125.1°C/W and R_θJB = 26°C/W in the YFP (DSBGA-6) package, rated for –40°C to +85°C operation.

FAQ

What is the maximum continuous current rating for the TPS22932BYFPR?

The TPS22932BYFPR is rated for 500 mA maximum continuous switch current across its full operating temperature range (–40°C to +85°C). This rating assumes proper PCB thermal design with adequate copper pour and is validated at 1.1 V to 3.6 V input voltage. Exceeding this current may cause thermal shutdown or permanent damage. The TPS22932BYFPR datasheet specifies absolute maximum ratings and derating curves for elevated ambient temperatures.

Does the TPS22932BYFPR require an external pull-up or pull-down resistor on its ON pins?

No, the TPS22932BYFPR does not require external pull-up or pull-down resistors on ON1, ON2, or ON3 pins. These inputs have internal biasing and defined logic thresholds (VT+ = 0.5–0.9 V, VT− = 0.2–0.7 V) that allow direct connection to VIN or GND for static configuration, or to 1.2–3.3 V GPIOs for dynamic control. Leaving them floating is prohibited per datasheet guidance.

How does the Quick Output Discharge (QOD) function work in the TPS22932BYFPR?

The TPS22932BYFPR integrates a 120 Ω (typ) internal resistor between VOUT and GND that activates automatically when the switch is disabled. This discharges the output node to ground within approximately 1 ms for typical 1–10 μF loads, preventing floating voltages that could cause leakage, latch-up, or erroneous wake-up in downstream circuits. No external components are needed to implement QOD in the TPS22932BYFPR.

Can the TPS22932BYFPR be used with a 1.2-V input supply?

Yes, the TPS22932BYFPR is fully specified for operation down to 1.1 V input, making it compatible with 1.2-V supplies. At VIN = 1.2 V, its r_ON is 115 mΩ (typ), supporting up to 500 mA with acceptable voltage drop. Its control inputs also accept 1.2-V logic levels directly, with VT+ = 0.5 V (min) and VT− = 0.2 V (min), ensuring robust interface to 1.2-V GPIOs without level translation.

What package type and dimensions does the TPS22932BYFPR use?

The TPS22932BYFPR uses a six-terminal wafer chip-scale package (DSBGA-YFP) with nominal body size 0.80 mm × 1.20 mm and 0.4-mm ball pitch. It features bottom-side solder bumps (not leads) and is designed for fine-pitch SMT assembly. The package is JEDEC-compliant and characterized for –40°C to +85°C operation, with thermal metrics including R_θJA = 125.1°C/W and R_θJB = 26°C/W.
