Texas Instruments TPS22925BNYPHR

Overview

TPS22925BNYPHR from Texas Instruments is a single-channel 3-A load switch IC with 9.2-mΩ on-resistance at 3.6 V, reverse current blocking, and integrated quick output discharge (QOD). It operates from 0.65 V to 3.6 V input, supports 1.5-/1.8-/2.5-/3.3-V logic control, and delivers controlled 97-µs rise time for inrush current management in space-constrained battery-powered systems.

For engineers reviewing the TPS22925BNYPHR datasheet, TPS22925BNYPHR pinout, TPS22925BNYPHR application, or TPS22925BNYPHR equivalent, key selection criteria include its 0.9 mm × 1.4 mm DSBGA-6 package, -40°C to +105°C operating range, 29 µA quiescent current at 3.6 V, and QOD-enabled fast output discharge for standby power reduction in portable electronics.

Technical Context

The TPS22925BNYPHR integrates an N-channel MOSFET with internal charge pump, control logic, and driver in a wafer chip-scale package. Its active-high ON pin accepts logic thresholds down to 0.9 V, enabling direct interface with low-voltage microcontrollers. The device implements reverse current blocking when disabled-requiring VIN ≥ 0.65 V or VOUT ≥ 0.65 V-and features hysteresis of 86 mV at 3.6 V for noise immunity.

Unlike non-QOD variants, TPS22925BNYPHR includes a 150-Ω internal pull-down resistor activated during disable, reducing output voltage decay time without external components. Its thermal design targets ≤125°C junction temperature, with R_θJA = 110.9°C/W and R_θJB = 30.4°C/W under standard PCB conditions.

FAQ

What is the maximum continuous current rating for TPS22925BNYPHR?

The TPS22925BNYPHR supports a maximum continuous switch current of 3 A at TA = 60°C, with pulsed current capability up to 4 A (100-µs pulse, 2% duty cycle). Derating applies above 60°C ambient; at 105°C, the device maintains reliable operation under full 3-A load with proper PCB thermal design.

Does TPS22925BNYPHR provide reverse current blocking?

Yes, TPS22925BNYPHR provides reverse current blocking when disabled, limiting reverse leakage to ≤6 µA at -40°C to +105°C. This feature activates when VIN ≥ 0.65 V or VOUT ≥ 0.65 V, making TPS22925BNYPHR suitable for power multiplexing and backup supply isolation.

What is the purpose of the Quick Output Discharge (QOD) function in TPS22925BNYPHR?

The QOD function in TPS22925BNYPHR activates a 150-Ω internal pull-down resistor between VOUT and GND when the ON pin is low, rapidly discharging load capacitance. This prevents floating outputs and reduces system-level standby current-critical for wearables and always-on sensor nodes.

Can TPS22925BNYPHR operate with a 1.2-V input supply?

Yes, TPS22925BNYPHR operates across 0.65 V to 3.6 V input. At VIN = 1.2 V, its on-resistance is 9.5 mΩ (typ), quiescent current is 20 µA (typ), and rise time is 86 µs-enabling use in low-voltage FPGA I/O banks or sub-1.8-V microcontroller peripherals.

What package type does TPS22925BNYPHR use, and what are its dimensions?

TPS22925BNYPHR uses a 6-pin DSBGA (Die Size Ball Grid Array) package designated YPH, measuring 0.9 mm × 1.4 mm with 0.5-mm ball pitch and 0.4-mm height. This wafer-level chip-scale package minimizes footprint and thermal resistance for high-density portable designs.
