Product details
Overview
TPS22916CNYFPT from Texas Instruments is a single-channel ultra-low-leakage load switch using a P-channel MOSFET, operating from 1 V to 5.5 V with 2-A continuous current capability, 60-mΩ typical RON at 5 V, 10 nA max OFF-state leakage, and slow turn-on timing (1400 µs at 5 V) to limit inrush current - deployed in smartphone power rail sequencing and wearable sensor subsystems.
For engineers reviewing the TPS22916CNYFPT datasheet, TPS22916CNYFPT pinout, TPS22916CNYFPT application, or TPS22916CNYFPT equivalent, key selection criteria include verified reverse-current blocking (–500 mA activation), integrated quick output discharge (150 Ω), smart ON-pin pulldown (750 kΩ typ.), and WCSP-4 package compatibility with space-constrained portable PCB layouts.
Technical Context
The TPS22916CNYFPT implements an actively controlled P-channel MOSFET gate driver with slew-rate-limited turn-on (5 mV/µs at 5 V) to suppress capacitive inrush, while maintaining true reverse-current blocking that disables the switch within 10 µs when VOUT exceeds VIN by >200 mV. Its smart ON-pin pulldown ensures reliable power-up sequencing without external biasing.
Unlike fast-turn-on variants (e.g., TPS22916B), the 'C' version delivers deterministic 1.4–6.5 ms turn-on across 1–5 V input range, enabling robust control of high-capacitance loads (e.g., 47 µF) while limiting peak inrush to ≤150 mA at 3.6 V - confirmed via Equation 2 (IRUSH = CL × SRON) in TI's application note.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 1 V to 5.5 V - supports direct interface with Li-ion battery, LDO outputs, and low-voltage logic rails without level shifting. |
| Continuous Current | 2 A - sustains full-rated load under worst-case thermal conditions (TA = 85°C, θJA = 193°C/W). |
| RON (5 V) | 60 mΩ typ., 100 mΩ max @ 85°C - enables <120 mW conduction loss at 2 A, critical for thermally constrained wearables. |
| OFF-State Leakage | 10 nA typ., 100 nA max - prevents standby current drain in always-on sensor nodes and battery-backed systems. |
| Turn-On Time (5 V) | 1400 µs - provides controlled voltage ramp to avoid supply droop and false resets in downstream ICs during hot-plug events. |
| Reverse Current Blocking | Activates at –500 mA, releases at +25 mV - eliminates backfeed from auxiliary supplies or charged capacitors into main rail. |
| Quick Output Discharge | 150 Ω typ. - discharges VOUT to GND within ~1.5 ms (for 10 µF load), preventing floating states and latch-up in powered-down peripherals. |
Pinout & Package
TPS22916CNYFPT uses a 0.78 mm × 0.78 mm, 0.4-mm pitch, 4-pin Wafer-Chip-Scale Package (WCSP, YFP) with 0.5-mm height - optimized for ultra-dense mobile PCBs and compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power Input | Main supply connection (1–5.5 V); must be decoupled with ≥1 µF ceramic capacitor placed adjacent to pin. |
| VOUT | Power Output | Switched output to load; integrates Quick Output Discharge (QOD) to ground when disabled. |
| GND | Ground Reference | Device substrate and return path for QOD current; requires low-inductance connection to system ground plane. |
| ON | Digital Enable | Active-high logic input (VIH ≥ 1 V, VIL ≤ 0.35 V); includes internal 750 kΩ pulldown to prevent floating at power-up. |
Key Features
| Feature | Design Value |
|---|---|
| Slow Turn-On Timing | 1400 µs at 5 V (5 mV/µs slew rate) - limits inrush current to ≤300 mA for 47 µF loads, eliminating need for external soft-start circuitry. |
| True Reverse Current Blocking | Auto-disables switch within 10 µs if VOUT > VIN + 200 mV - prevents backfeed from USB OTG, battery chargers, or hot-swapped modules. |
| Ultra-Low OFF-State Leakage | 10 nA typ. (100 nA max) - preserves battery life in multi-week standby modes for IoT sensors and hearables. |
| Integrated Quick Output Discharge | 150 Ω discharge path - ensures VOUT settles to GND within milliseconds after disable, avoiding undefined logic states in connected peripherals. |
| Smart ON-Pin Pulldown | 750 kΩ internal resistor - holds ON low during power-up sequencing until host MCU asserts valid enable signal, eliminating external pull-down resistors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS22916BNYFPT | Faster turn-on (115 µs at 5 V), same RON, QOD, and package - no change to BOM footprint. | Suitable for low-capacitance loads (<10 µF) where rapid enable is required, e.g., microSD card power control. | Select when inrush current is not a concern and system timing demands sub-200 µs rail activation. |
| TPS22967DSGR | Higher current (6 A), larger 8-pin WSON package, no integrated QOD, 30-mΩ RON at 5 V. | Targets higher-power subsystems like USB-C PD sink rails or SSD power gating - incompatible pinout and layout. | Choose only when >2 A capability is mandatory and board area allows 2.0 × 2.0 mm WSON; requires redesign. |
Compared with TPS22916BNYFPT, the TPS22916CNYFPT trades speed for inrush control - critical for 47 µF+ loads - while TPS22967DSGR offers higher current but sacrifices integration (no QOD, no RCB) and miniaturization.

FAQ
What is the maximum continuous current rating for the TPS22916CNYFPT?
The TPS22916CNYFPT supports 2 A of continuous current across its full operating temperature range (–40°C to +85°C), validated under worst-case thermal conditions with θJA = 193°C/W. This rating assumes proper PCB copper pour and airflow; derating applies above 60°C ambient.
Does the TPS22916CNYFPT include reverse current blocking, and how does it operate?
Yes, the TPS22916CNYFPT features always-on true reverse current blocking (RCB). When VOUT exceeds VIN by more than 200 mV, the device disables the pass FET within 10 µs. It remains off until VOUT drops below VIN + 25 mV, then resumes normal operation with controlled slew rate - confirmed in Section 8.3.3 of the datasheet.
What is the purpose of the "slow timing" in the TPS22916CNYFPT variant?
The slow timing in the TPS22916CNYFPT (e.g., 1400 µs turn-on at 5 V) deliberately limits slew rate to 5 mV/µs, suppressing inrush current during capacitive load charging. This prevents supply rail collapse and false resets - especially critical for 47 µF+ loads in smartphones and tablets, as demonstrated in Application Note SLVSDO5F Section 9.2.2.
Is the TPS22916CNYFPT compatible with 1.2-V GPIO control signals?
Yes, the TPS22916CNYFPT ON pin accepts 1.2-V logic-high signals: VIH is specified as ≥1 V over temperature, and ION leakage is ≤10 nA. Its smart pulldown (750 kΩ) ensures reliable low-state hold during power-up, making it interoperable with modern ultra-low-voltage MCUs without external level shifters.
How does the Quick Output Discharge (QOD) function in the TPS22916CNYFPT?
The TPS22916CNYFPT integrates a 150 Ω (typ.) discharge path between VOUT and GND when disabled. This actively pulls down output voltage - for example, discharging a 10 µF load to <10% of VIN in ~1.5 ms - preventing floating states that could cause logic glitches or latch-up in downstream peripherals.
