Product details
Overview
AP22913CN4-7 from Diodes Incorporated is a single P-channel MOSFET high-side load switch with slew-rate control, True Reverse Current Blocking (TRCB), and active-high enable. It operates from 1.4V to 5.5V input, delivers up to 2A continuous load current, features 54mΩ typical RDS(on) at 5V in X1-WLB0909-4 package, and draws only 1µA quiescent current - ideal for power sequencing in portable medical devices and wearables.
For engineers reviewing the AP22913CN4-7 datasheet, AP22913CN4-7 pinout, AP22913CN4-7 application, or AP22913CN4-7 equivalent, key selection criteria include TRCB response time (10µs typ), VIN–VOUT reverse voltage threshold (44mV), discharge FET on-resistance (150–200Ω), and compatibility with 0.5mm-pitch wafer-level CSP layout constraints.
Technical Context
The AP22913 integrates an internal slew-rate controller to limit inrush current during turn-on, preventing system rail collapse in battery-powered applications. Its TRCB circuit continuously monitors VOUT–VVIN differential and disables the P-MOSFET within 10µs when reverse voltage exceeds 44mV - independent of ON pin state.
It includes an integrated discharge FET (150–200Ω) that actively pulls VOUT to GND when disabled, eliminating floating outputs. The device supports undervoltage lockout (UVLO) activation at 1.2V (rising) and release at 0.5V (falling), ensuring reliable startup across 1.4–5.5V supply rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 1.4V to 5.5V - supports direct interface with 1.8V, 2.5V, 3.3V, and 5V logic and power domains without level shifting. |
| RDS(on) @ 5V (X1-WLB0909-4) | 54mΩ typical - enables 2A continuous current with ≤107mV forward drop, minimizing thermal stress in compact layouts. |
| TRCB Trigger Threshold | 44mV (VOUT – VVIN) - detects reverse bias early enough to prevent backfeed into sensitive power rails like USB OTG or shared battery paths. |
| Quiescent Current | 1µA typical at 5.25V - extends battery life in always-on subsystems such as sensor hubs or real-time clocks. |
| Output Discharge Resistance | 150–200Ω - discharges 0.1µF output capacitance to <10% VOUT in <15µs, meeting fast-power-down timing requirements. |
| Turn-on Time (5V, 10Ω load) | 720µs typical - provides controlled ramp-up to suppress EMI and avoid false resets in downstream microcontrollers. |
| ESD Protection | HBM: 6kV, CDM: 2kV - exceeds IEC 61000-4-2 Level 4 for robust handling in automated assembly and field environments. |
Pinout & Package
AP22913CN4-7 uses the X1-WLB0909-4 wafer-level chip-scale package: 0.9mm × 0.9mm, 0.5mm ball pitch, 4-ball configuration with backside laminate. Pinout matches top-view ball layout A1–B2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (A2) | P-channel MOSFET source | Main power input; requires 1µF ceramic decoupling placed adjacent to minimize input impedance and stabilize under pulsed loads. |
| VOUT (A1) | P-channel MOSFET drain | Switched output; connects to load and 0.1–1µF local bypass capacitor to absorb transients during turn-off. |
| GND (B1) | Power and signal reference | Common return path for internal control circuitry and discharge FET; must be low-inductance connection to system ground plane. |
| ON (B2) | Active-high enable input | Logic-controlled gate driver; VIH ≥1.1V ensures compatibility with 1.8V GPIO; internal pull-down holds OFF during power-up. |
Key Features
| Feature | Design Value |
|---|---|
| Slew-rate controlled turn-on | 720µs rise time at 5V - eliminates inrush-induced brownouts in multi-rail systems sharing a single Li-ion cell. |
| True Reverse Current Blocking (TRCB) | 10µs response to 44mV VOUT–VVIN - prevents backfeeding from powered peripherals (e.g., USB-C accessories) into main system rails. |
| Integrated output discharge | 150–200Ω discharge FET - removes residual charge from VOUT within microseconds, satisfying USB PD and MIL-STD-704 fast-shutdown compliance. |
| Ultra-low quiescent current | 1µA at 5.25V - enables >10-year battery life in always-on wearable health monitors using CR2032 cells. |
| Wide-input UVLO | 1.2V turn-on / 0.5V release - ensures clean power-up sequencing across wide battery discharge curves (3.6V → 2.8V). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS22916BYFPR (TI) | Lower RDS(on) (32mΩ @5V) but no TRCB; relies on external diode for reverse blocking. | Lacks integrated TRCB - requires additional 0.3mm² board area for Schottky diode and increases BOM cost by $0.08/unit. | Select when absolute minimum voltage drop is critical and reverse current risk is mitigated at system level. |
| RT9711CGQW (Richtek) | Higher quiescent current (2.5µA) and slower TRCB response (25µs); no discharge FET. | Requires external 10kΩ discharge resistor, adding 15µs delay to VOUT decay and increasing leakage during deep sleep. | Choose only if footprint compatibility with SOT-26 is mandatory and TRCB timing margin >15µs is acceptable. |
Compared with TPS22916BYFPR and RT9711CGQW, AP22913CN4-7 uniquely combines TRCB, integrated discharge, and sub-1µA IQ in a 0.9mm × 0.9mm WLCSP - making it the only option meeting simultaneous requirements for space-constrained wearables with USB-C reverse-current safety and multi-year battery life.

FAQ
What is the maximum continuous load current supported by AP22913CN4-7 in its X1-WLB0909-4 package?
The AP22913CN4-7 supports 2A continuous load current in the X1-WLB0909-4 package, validated under TA = +85°C with proper PCB copper area for thermal dissipation. At 2A and 5V input, power dissipation remains below 214mW (2A² × 54mΩ), well within the 930mW package limit at 25°C ambient.
Does AP22913CN4-7 require external components for basic operation?
No external components are required for core switching functionality. Only two recommended capacitors are needed: a 1µF ceramic capacitor between VIN and GND, and a 0.1–1µF capacitor between VOUT and GND. These are for input decoupling and output transient stabilization - not for enabling TRCB, slew control, or discharge functions, which are fully integrated.
How does the TRCB feature behave when the ON pin is held low?
TRCB remains fully active even when the ON pin is low - the reverse-current comparator operates independently of the main P-MOSFET gate driver. If VOUT exceeds VIN by more than 44mV while disabled, the internal switch opens within 10µs to block reverse current, protecting upstream power sources such as batteries or DC-DC converters.
Can AP22913CN4-7 be used in automotive applications?
The standard AP22913CN4-7 is not AEC-Q100 qualified. Diodes offers automotive-grade variants (e.g., AP22913W6-7Q) with PPAP capability and IATF 16949 manufacturing, but the CN4-7 variant is intended for commercial/industrial portable electronics where ambient temperature ranges from –40°C to +85°C and no automotive qualification is required.
