Product details
Overview
TPS22924BYZPRB from Texas Instruments is a 2-A, ultra-low-RON load switch IC featuring an integrated N-channel MOSFET, controlled slew-rate turn-on (96 µs at 3.6 V), 18.3 mΩ on-resistance at 3.6 V input, and quick-output discharge via internal 1250-Ω pulldown resistor - deployed in battery-powered portable electronics to manage power rail sequencing and suppress inrush current.
For engineers reviewing the TPS22924BYZPRB datasheet, TPS22924BYZPRB pinout, TPS22924BYZPRB application, or TPS22924BYZPRB equivalent, this page delivers verified electrical specs, package mapping, functional context for low-voltage GPIO control, and validated alternatives for load-switching designs requiring <100 µs rise time and sub-25 mΩ RON.
Technical Context
The TPS22924BYZPRB implements a charge-pump–biased NMOS pass element enabling full enhancement down to 0.75 V input while maintaining low RON across its 0.75–3.6 V operating range. Its fixed 96 µs rise time (VIN = 3.6 V) is internally generated without external RC components, ensuring repeatable inrush control.
It integrates active output discharge (1250 Ω pulldown), low-threshold ON pin compatible with 1.2 V/1.8 V/2.5 V/3.3 V GPIOs, and shutdown leakage <3.5 µA - all in a 0.9 mm × 1.4 mm DSBGA-6 package with backside coating for mechanical robustness.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Switch Current | 2 A continuous - supports USB-powered peripherals, display bias rails, and sensor subsystems without thermal derating at 85°C ambient. |
| On-Resistance (RON) | 18.3 mΩ at VIN = 3.6 V - limits voltage drop to ≤36.6 mV at 2 A, preserving downstream regulation margin. |
| Rise Time (tr) | 96 µs at VIN = 3.6 V - enforces ~37.5 V/ms slew rate to cap inrush into 1 µF load at <40 mA. |
| Input Voltage Range | 0.75 V to 3.6 V - enables direct integration after buck converters, LDOs, or single-cell Li-ion/LiFePO4 sources. |
| Shutdown Current | 3.5 µA max - minimizes battery drain in always-on standby modes of portable medical or GPS devices. |
| ESD Rating | ±5000 V HBM - meets IEC 61000-4-2 Level 4 system-level ESD immunity requirements without external protection. |
| Operating Temp | –40°C to +85°C - qualified for industrial handhelds, point-of-sale terminals, and automotive infotainment accessories. |
Pinout & Package
TPS22924BYZPRB uses a 0.9 mm × 1.4 mm, 0.5-mm pitch DSBGA-6 package with backside coating (YZP variant) for enhanced crack resistance. Pin 1 identifier denotes Pb-free solder bumps.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| C1 | GND | Power ground reference; must be low-impedance connection to PCB ground plane for stable switching and EMI control. |
| C2 | ON | Active-high enable input; accepts 0.6 V min VIH at 3.3 V VIN - directly driven by MCU GPIO without level-shifting. |
| A1, B1 | VOUT | Switched output node; connects to load capacitance and downstream circuitry; includes integrated 1250-Ω discharge path to GND when OFF. |
| A2, B2 | VIN | Input power rail; requires local 1 µF ceramic bypass capacitor to minimize inrush-induced supply dip and ensure stable charge-pump operation. |
Key Features
| Feature | Design Value |
|---|---|
| Controlled Slew Rate | Fixed 96 µs rise time eliminates need for external RC timing networks - reduces BOM count and layout sensitivity. |
| Integrated Output Discharge | 1250-Ω internal pulldown discharges VOUT to ~10% of rail within microseconds - prevents floating outputs and unintended wake-up in sleep states. |
| Low-Voltage GPIO Compatibility | ON pin VIH threshold as low as 0.6 V at 3.3 V VIN - interoperates with modern ultra-low-power MCUs (e.g., MSP430, nRF52) without pull-up resistors. |
| Ultra-Small Footprint | 0.9 mm × 1.4 mm DSBGA-6 occupies <1.3 mm² PCB area - ideal for space-constrained wearables and compact IoT sensors. |
| Charge-Pump NMOS Architecture | Enables sub-1 V operation while sustaining RON <23 mΩ at 0.75 V - outperforms discrete FET+driver solutions in low-input applications. |
Applications
| Portable Medical Devices | Smartphones |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar load-switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS22924CYZPRB | 800 µs rise time (vs. 96 µs); identical RON, package, and pinout. | Better suited for high-capacitance loads (>10 µF) where slower turn-on is acceptable to eliminate inrush entirely. | Select TPS22924CYZPRB when minimizing peak inrush dominates over fast enable timing. |
| TPS22965DSGR | Higher 3.5 A rating, 12.5 mΩ RON at 3.6 V, WSON-6 package (1.5 mm × 2.0 mm). | Requires larger PCB footprint but supports higher-current modules like Wi-Fi/BT coexistence circuits. | Choose TPS22965DSGR when >2 A continuous current or lower RON is required, accepting 2.3× larger area. |
Compared with TPS22924CYZPRB and TPS22965DSGR, the TPS22924BYZPRB uniquely balances ultra-fast 96 µs enable timing, minimal 1.26 mm² footprint, and 2 A capability - making it optimal for space-constrained, latency-sensitive portable systems.

FAQ
What is the maximum continuous current rating for the TPS22924BYZPRB?
The TPS22924BYZPRB is rated for 2 A maximum continuous switch current over the full –40°C to +85°C operating temperature range, as specified in the Absolute Maximum Ratings table. This rating assumes proper PCB thermal design with adequate copper pour and via stitching to maintain junction temperature within safe limits under sustained load.
Does the TPS22924BYZPRB require an external pull-up resistor on the ON pin?
No, the TPS22924BYZPRB does not require an external pull-up resistor on the ON pin. Its VIH threshold is as low as 0.6 V at 3.3 V VIN, allowing direct interface with standard 1.2 V, 1.8 V, 2.5 V, or 3.3 V GPIO outputs. Leaving the ON pin unconnected is prohibited - it must be actively driven high or low.
How does the output discharge function work in the TPS22924BYZPRB?
The TPS22924BYZPRB integrates a 1250-Ω pulldown transistor between VOUT and GND that activates automatically when the ON pin is driven low. It discharges the output rail to approximately 10% of VIN within microseconds, then disconnects to limit shutdown current to ≤3.5 µA - preventing floating nodes and unintended wake-up events.
What is the purpose of the backside coating on the TPS22924BYZPRB package?
The backside coating on the TPS22924BYZPRB's YZP DSBGA package increases mechanical strength and resistance to cracking during board flexure or thermal cycling. Texas Instruments explicitly recommends coated variants like TPS22924BYZPRB for new designs to improve long-term reliability in portable equipment subjected to mechanical stress.
Can the TPS22924BYZPRB operate from a 0.9 V input supply?
Yes, the TPS22924BYZPRB supports input voltages as low as 0.75 V. At VIN = 0.9 V, its typical RON is 22.7 mΩ and rise time is 81 µs (per Section 7.7). This enables use after ultra-low-dropout regulators or in single-cell NiMH/LiFePO4 systems where minimum operating voltage is critical.
