Product details
Overview
TPS22924BYZR from Texas Instruments is a single-channel, 2-A load switch IC featuring an integrated N-channel MOSFET with 18.3 mΩ on-resistance at 3.6 V input, controlled slew-rate turn-on (96 µs rise time), and quick output discharge. It operates from 0.75 V to 3.6 V input voltage and delivers low shutdown current (3.5 µA) for battery-powered portable electronics.
For engineers reviewing the TPS22924BYZR datasheet, TPS22924BYZR pinout, TPS22924BYZR application, or TPS22924BYZR equivalent, this page provides verified specifications, package mapping, functional context, and real-world implementation guidance - including inrush current management, output discharge behavior, and GPIO-compatible control interface.
Technical Context
The TPS22924BYZR implements an NMOS pass switch driven by an internal charge pump to achieve low RON across its full 0.75–3.6 V input range. Its fixed 96 µs rise time (at VIN = 3.6 V) is internally set to limit inrush current without external RC networks.
It integrates an active output pulldown transistor (1250 Ω) that discharges VOUT to ~10% of rail before disconnecting, minimizing off-state leakage. Control logic accepts low-threshold ON signals compatible with 1.2 V/1.8 V/2.5 V/3.3 V GPIOs, and the device requires no external components beyond input/output capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 0.75 V to 3.6 V - supports ultra-low-voltage rails (e.g., Li-ion single-cell, LDO outputs) and standard 1.8 V/2.5 V/3.3 V domains. |
| Max Continuous Current | 2 A - enables power gating of high-current peripherals like displays, sensors, or RF modules in portable systems. |
| RON @ VIN = 3.6 V | 18.3 mΩ - yields only 73 mV drop at 4 A peak, minimizing conduction loss and thermal stress. |
| Rise Time @ VIN = 3.6 V | 96 µs - limits inrush current to ≤40 mA with 1 µF output capacitance, eliminating need for external soft-start circuitry. |
| Shutdown Current | 3.5 µA - preserves battery life in always-on standby modes (e.g., Bluetooth LE wake-up circuits). |
| ESD Rating (HBM) | ±5000 V - meets industrial-grade robustness requirements without additional protection components. |
| Operating Temperature | –40°C to +85°C - qualified for consumer, medical, and industrial portable equipment environments. |
Pinout & Package
TPS22924BYZR uses a 0.9 mm × 1.4 mm DSBGA-6 (YZ) package with 0.5-mm pitch and Pb-free SnAgCu bump finish. The package features backside coating optional (not present on YZ variant), optimized for space-constrained PCB layouts in handheld devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| C1 | GND | Power ground reference; must be connected to low-impedance system ground plane to ensure stable switching and EMI control. |
| C2 | ON | Active-high enable input; logic threshold compatible with 1.2 V GPIOs; must not float - tie to GND or controller for defined state. |
| A1, B1 | VOUT | Switched output node; connects to downstream load; requires local ceramic decoupling (≥1 µF) near pin for stability. |
| A2, B2 | VIN | Input power rail; bypassed with ≥1 µF ceramic capacitor to GND close to pin to suppress inrush-induced supply dip. |
Key Features
| Feature | Design Value |
|---|---|
| Controlled Slew Rate | 96 µs VOUT rise time at 3.6 V - eliminates external soft-start components while ensuring <40 mA inrush into 1 µF loads. |
| Integrated Output Discharge | 1250 Ω pulldown FET - actively drains VOUT to ~10% of rail during turn-off, preventing floating outputs and enabling fast system reset. |
| Low-Voltage Control Interface | ON pin accepts 0.9 V logic-high threshold - interoperable with 1.2 V/1.8 V microcontrollers without level-shifting. |
| Ultra-Small Footprint | 0.9 mm × 1.4 mm DSBGA-6 - saves >60% board area vs. comparable SOT-23 or WSON packages, critical for wearables and compact IoT nodes. |
| Charge-Pump Driven NMOS | Enables 18.3 mΩ RON at 3.6 V without external gate drive - achieves low conduction loss while maintaining single-supply operation. |
Applications
| Smartphones | Portable Medical Devices |

Equivalent & Alternatives
The following parts are listed as comparable options for similar load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS22924CYZPR | 800 µs rise time (vs. 96 µs); identical RON, package, and control interface. | Better suited for ultra-low-inrush scenarios (e.g., >10 µF output caps) where slower turn-on is acceptable. | Select TPS22924CYZPR when inrush current must be <5 mA; otherwise TPS22924BYZR offers faster response with same footprint. |
| TPS22965YBHR | Higher 3.5 A rating, 14 mΩ RON at 3.6 V, WSON-6 package (2.0 mm × 2.0 mm), 200 µs rise time. | Targets higher-current applications (e.g., SSD power rails) but requires larger PCB area and different layout. | Choose TPS22965YBHR only if >2 A continuous current or lower RON is required; not pin-compatible with TPS22924BYZR. |
Compared with TPS22924CYZPR and TPS22965YBHR, the TPS22924BYZR uniquely balances sub-100 µs controlled turn-on, ultra-compact 0.9×1.4 mm CSP, and 2 A capability - making it optimal for space-constrained, battery-sensitive designs where moderate inrush control suffices.

FAQ
What is the maximum continuous current rating for the TPS22924BYZR?
The TPS22924BYZR supports a maximum continuous switch current of 2 A over the full operating temperature range (–40°C to +85°C). This rating is validated under recommended PCB layout conditions with adequate copper pour for thermal dissipation. Peak pulsed current is rated at 4 A for 100-µs pulses at 2% duty cycle.
Does the TPS22924BYZR require an external pull-up or pull-down resistor on the ON pin?
No - the ON pin of the TPS22924BYZR has no internal pull-up or pull-down. It must be actively driven high or low by a controller GPIO; leaving it floating is prohibited. For default-off behavior, tie ON to GND through a 100-kΩ resistor or drive it directly from a microcontroller pin configured as open-drain or push-pull.
How does the output discharge function work in the TPS22924BYZR?
The TPS22924BYZR integrates a dedicated 1250 Ω pulldown transistor that activates automatically when the ON pin is deasserted. It discharges VOUT to approximately 10% of VIN within microseconds, then disconnects to minimize shutdown current. This prevents floating outputs and enables deterministic reset timing in battery-powered systems.
Can the TPS22924BYZR operate from a 0.9-V input supply?
Yes - the TPS22924BYZR is fully specified down to 0.75 V input. At VIN = 0.9 V, typical RON is 22.7 mΩ and rise time increases to 160 µs (TA = 25°C). All electrical characteristics, including ON-pin threshold and quiescent current, remain valid across the entire 0.75–3.6 V range.
Is the TPS22924BYZR pin-compatible with other devices in the TPS22924x family?
Yes - all TPS22924x variants (including TPS22924BYZR, TPS22924CYZPR, and TPS22924BYZZR) share identical DSBGA-6 pinout, package dimensions, and terminal assignments. Only the rise time and top-side marking differ; no PCB redesign is needed when substituting between B- and C-version load switches.
