Texas Instruments TPS22924DYZPR

Overview

TPS22924DYZPR from Texas Instruments is a single-channel, 2-A load switch IC with integrated NMOS FET, controlled slew-rate turn-on (6200 µs at 3.6 V), 18.3 mΩ on-resistance at 3.6 V input, and quick output discharge via 1250 Ω internal pulldown resistor - designed for inrush current limiting in portable power rail management.

For engineers reviewing the TPS22924DYZPR datasheet, TPS22924DYZPR pinout, TPS22924DYZPR application, or TPS22924DYZPR equivalent, key selection criteria include input voltage range (0.75–3.6 V), shutdown current (4.0 µA), thermal resistance (R_θJA = 123 °C/W), and DSBGA-6 package compatibility with space-constrained handheld designs.

Technical Context

The TPS22924DYZPR integrates an N-channel MOSFET with an internal charge pump to enable low R_ON operation down to 0.75 V input, while its controlled rise time prevents system-level voltage droop during hot-swap events. The device implements active-high ON control with logic-compatible thresholds (VIH = 0.6 V min at VIN = 1.0 V) and automatic output discharge upon turn-off.

Its functional block includes dedicated control logic, gate driver, charge pump supply, and a 1250 Ω output pulldown transistor that discharges VOUT to ~10% of rail before disconnecting to minimize shutdown leakage. Thermal performance is characterized for –40°C to 85°C free-air operation with R_θJB = 22.8 °C/W on standard PCB layouts.

FAQ

What is the maximum continuous current rating for the TPS22924DYZPR?

The TPS22924DYZPR supports a maximum continuous switch current of 2 A over the full operating temperature range (–40°C to +85°C). This rating is validated with proper PCB thermal design - including adequate copper pour and thermal vias - and assumes VIN ≥ 0.75 V. At 85°C ambient, derating may apply depending on layout; consult the dissipation ratings table for thermal limits.

Does the TPS22924DYZPR include an integrated output discharge function?

Yes, the TPS22924DYZPR includes an integrated 1250 Ω output pulldown resistor that activates automatically when the ON pin is driven low. This discharges VOUT to approximately 10% of the input rail voltage before disconnecting to minimize shutdown current. The feature eliminates the need for external discharge circuitry in applications where floating outputs could cause data corruption or unintended wake-up events.

What is the typical on-resistance of the TPS22924DYZPR at 1.8 V input?

The typical on-resistance of the TPS22924DYZPR at VIN = 1.8 V is 19.6 mΩ, measured at I_OUT = –200 mA and T_A = 25°C. This value increases slightly at temperature extremes and under higher load currents due to MOSFET channel resistance variation. At –40°C, R_ON is ~18.2 mΩ; at +85°C, it rises to ~21.5 mΩ under identical test conditions.

Can the TPS22924DYZPR be used with a 1.2-V GPIO control signal?

Yes, the TPS22924DYZPR's ON pin has a low-voltage-compatible threshold: at VIN = 1.2 V, the minimum high-level input voltage (VIH) is 0.9 V, well within the output swing of standard 1.2-V GPIOs. The device does not require external level-shifting circuitry and maintains reliable turn-on behavior across all supported input voltages (0.75–3.6 V).

What package type and dimensions does the TPS22924DYZPR use?

The TPS22924DYZPR uses a 6-pin DSBGA (Die Size Ball Grid Array) package designated YZP, with nominal body dimensions of 0.9 mm × 1.4 mm and a 0.5-mm ball pitch. Total package height is ≤0.5 mm. The part marking is "DL", and it is supplied in tape-and-reel format (3000 units per reel, 9.2-mm reel width).
