Product details
Overview
TPS22924BYZZR from Texas Instruments is a single-channel, 2-A N-channel load switch with controlled slew rate, designed for low-voltage power rail switching in portable electronics. It features 18.3 mΩ on-resistance at 3.6 V input, 96 µs rise time, integrated output discharge (1250 Ω), and operates from 0.75 V to 3.6 V - enabling use in battery-powered GPS devices and medical wearables where inrush current limiting and standby leakage minimization are critical.
For engineers reviewing the TPS22924BYZZR datasheet, TPS22924BYZZR pinout, TPS22924BYZZR application, or TPS22924BYZZR equivalent, this page delivers verified electrical parameters, package mapping to DSBGA-6 (0.9 mm × 1.4 mm, 0.35 mm height), functional role in power sequencing, and validated alternative options for low-RON load switching in space-constrained designs.
Technical Context
The TPS22924BYZZR integrates an N-channel MOSFET with an internal charge pump to ensure full enhancement across its 0.75–3.6 V input range, eliminating external gate drive circuitry. Its 96 µs rise time at 3.6 V is fixed by internal slew-rate control, not adjustable externally.
It includes a dedicated output pulldown transistor that discharges VOUT to ~10% of rail voltage during turn-off, then auto-disconnects to limit shutdown current to 3.5 µA. The ON pin accepts standard GPIO logic thresholds (VIH ≥ 0.9 V at VIN = 0.75 V), supporting direct interface with 1.2-V/1.8-V microcontrollers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 0.75 V to 3.6 V - supports Li-ion, Li-poly, and regulated 1.2-V/1.8-V rails without level-shifting. |
| Max Continuous Current | 2 A - sustains full load under worst-case thermal conditions (TA = –40°C to 85°C). |
| On-Resistance (RON) | 18.3 mΩ at VIN = 3.6 V - limits voltage drop to ≤73 mV at 4 A peak, enabling tight output regulation. |
| Rise Time (tr) | 96 µs at VIN = 3.6 V - controls inrush to ≤40 mA into 1 µF load, preventing supply sag and false resets. |
| Shutdown Current | 3.5 µA - minimizes battery drain in always-on systems like portable medical monitors. |
| ESD Rating (HBM) | ±5000 V - meets industrial handling requirements without additional protection circuitry. |
| Operating Temperature | –40°C to +85°C - qualified for consumer and industrial portable equipment environments. |
Pinout & Package
TPS22924BYZZR uses a 0.9 mm × 1.4 mm, 0.35-mm-height DSBGA-6 package (YZZ variant) with solder bumps on bottom side. Pin 1 identifier is marked with • (Pb-free). Backside coating is absent per orderable part marking "7A" and Device Comparison Table.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| C1 | GND | Power ground reference; must be connected to low-impedance system ground plane for thermal and EMI performance. |
| C2 | ON | Active-high enable input; VIH threshold as low as 0.9 V enables direct connection to 1.2-V I/O domains. |
| A1, B1 | VOUT | Switched output node; connects to downstream load; requires local ceramic decoupling (≥1 µF) near pin. |
| A2, B2 | VIN | Input power rail; bypassed with ≥1 µF ceramic capacitor to GND to suppress inrush-induced supply dip. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Output Discharge | 1250 Ω pulldown resistor actively discharges VOUT to ~10% of rail within microseconds after turn-off, preventing floating outputs and latch-up in downstream circuits. |
| Controlled Slew Rate | Fixed 96 µs rise time eliminates need for external RC networks while guaranteeing predictable inrush current (<40 mA into 1 µF), simplifying layout and validation. |
| Low Threshold ON Input | VIH = 0.9 V minimum at VIN = 0.75 V allows seamless interfacing with ultra-low-voltage MCUs (e.g., MSP430, nRF52) without level shifters. |
| Ultra-Small Footprint | 0.9 mm × 1.4 mm DSBGA-6 package saves >70% board area vs. comparable SOIC-8 switches, critical for wearables and hearing aids. |
| Charge Pump Gate Drive | Internal charge pump ensures NMOS fully enhanced down to 0.75 V input, achieving stable RON without external VGS boost circuitry. |
Applications
| Portable Medical Sensors | GPS Tracking Modules |
|---|---|

Use Value: 2 A rating handles peak flash current; 1250 Ω output discharge prevents ghost illumination after turn-off. |
Use Scenario: Managing power to magnetic stripe reader (MSR) and contactless (NFC) modules in handheld POS terminals powered by 3.6 V Li-ion. IC Role / Device Role / Timing Role: Independent rail switch for peripheral subsystems; supports hot-plug detection and secure power-down on transaction completion. Use Value: ±5000 V HBM ESD rating withstands field handling; 0.75 V min input supports brown-out operation during battery depletion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar load switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS22924BYZR | Same RON, rise time, and specs; differs only in package height (0.4 mm vs. 0.35 mm YZZ) and top-side marking (_5N_ vs. _7A_). | Compatible in all PCB layouts using YZ/YZZ footprints; no rework needed if board supports 0.35–0.4 mm bump height tolerance. | Select when sourcing flexibility or legacy design reuse is prioritized over minimal height reduction. |
| TPS22924CYZPR | Slower 800 µs rise time (vs. 96 µs), identical RON, package, and voltage range; optimized for ultra-low inrush rather than speed. | Suitable for high-capacitance loads (>10 µF) where slower ramp prevents supply collapse, but unsuitable for time-critical subsystems. | Choose only when inrush current must be <5 mA - not for GPS, camera, or real-time sensor applications requiring fast enable. |
Compared with TPS22924BYZZR, TPS22924BYZR offers identical electrical behavior with minor mechanical variation, while TPS22924CYZPR trades speed for extreme inrush suppression - making the former a drop-in option and the latter a functionally distinct alternative for specific low-slew use cases.

FAQ
What is the maximum continuous current rating for the TPS22924BYZZR?
The TPS22924BYZZR supports a maximum continuous switch current of 2 A across its full operating temperature range (–40°C to +85°C), as specified in the Absolute Maximum Ratings table. This rating assumes proper PCB thermal design with adequate copper area and airflow; derating applies above 70°C ambient per thermal resistance data (RθJA = 123°C/W).
Does the TPS22924BYZZR require an external pull-up resistor on the ON pin?
No, the TPS22924BYZZR does not require an external pull-up resistor on the ON pin. The ON input has internal biasing and is designed to be driven directly by microcontroller GPIOs. Leaving it floating is prohibited per datasheet guidance, but active driving - either high or low - is sufficient; no external passive components are needed for basic operation.
What is the purpose of the output pulldown feature in the TPS22924BYZZR?
The TPS22924BYZZR includes an integrated 1250 Ω output pulldown transistor that activates automatically when the switch turns off. It discharges VOUT to approximately 10% of the input rail voltage within microseconds, preventing floating outputs, unintended wake-up of downstream ICs, and potential latch-up in mixed-signal systems - all without requiring external discharge circuitry.
Can the TPS22924BYZZR operate from a 1.2-V supply?
Yes, the TPS22924BYZZR is fully specified to operate from 1.2 V input. At VIN = 1.2 V, its typical on-resistance is 19.4 mΩ, quiescent current is 95 µA, and VIH (ON pin high threshold) is 0.6 V - ensuring reliable switching and low-power operation in 1.2-V I/O domain systems such as energy-harvesting sensors and ultra-low-voltage MCUs.
Is the TPS22924BYZZR pin-compatible with other variants in the TPS22924x family?
Yes, all TPS22924x variants - including TPS22924BYZZR, TPS22924BYZR, and TPS22924CYZPR - share identical DSBGA-6 pinout (YZ/YZP/YZZ packages), same footprint, and identical terminal functions (VIN, VOUT, ON, GND). Mechanical differences (height, backside coating) do not affect electrical connectivity or PCB layout compatibility.
