Product details
Overview
AP22916CCA4-7 from Diodes Incorporated is a single-channel, P-channel ultra-low-leakage load switch IC designed for power sequencing and rail isolation in space-constrained portable systems. It operates from 1.3V to 5.5V input, delivers up to 2A continuous load current, features 60mΩ typical RDS(ON) at 5V, and integrates True Reverse Current Blocking (TRCB) with 25mV trigger threshold and 10μs response time. It is used in smartphone PMIC subsystems to isolate backup battery rails during sleep mode.
For engineers reviewing the AP22916CCA4-7 datasheet, AP22916CCA4-7 pinout, AP22916CCA4-7 application, or AP22916CCA4-7 equivalent, key selection criteria include its 0.5µA quiescent current, active-high ON pin with 1.0V VIH minimum, TRCB functionality, U-WLB0808-4 (Type B) 0.78mm × 0.78mm package, and slow-turn-on timing profile (1.4ms tON at 5V) for inrush control.
Technical Context
The AP22916CCA4-7 implements a smart P-MOSFET load switch with integrated driver, TRCB comparator, and output discharge path. Its ON pin accepts active-high logic signals with VIH ≥ 1.0V and VIL ≤ 0.35V, enabling direct interface with 1.8V/3.3V GPIOs without level-shifting.
TRCB activates when VOUT exceeds VIN by >25mV, sinking up to –650mA reverse current while blocking forward conduction - critical for multi-rail systems where VOUT may be back-driven. The device also includes a 750kΩ internal pull-down on the ON pin and a 150Ω output discharge resistor activated during disable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 1.3V to 5.5V - supports direct integration into 1.3V, 1.8V, 2.5V, 3.3V, 3.6V, and 5V system rails without external regulators. |
| RDS(ON) @ 5V | 54mΩ typical - enables 2A continuous operation with <110mV forward drop, minimizing power loss and thermal rise. |
| Quiescent Current | 0.5µA typical - reduces standby power in always-on subsystems such as real-time clock or sensor hubs. |
| TRCB Trigger Threshold | 25mV - detects small reverse voltage differentials early, preventing battery drain or LDO instability in stacked supply architectures. |
| tON @ 5V | 1400µs typical - provides controlled slew rate (5mV/µs) to limit inrush current into large capacitive loads like display bias rails. |
| Output Discharge Resistance | 150Ω - actively discharges VOUT capacitance within ~1ms (for 1µF), eliminating floating nodes and enabling fast power-state transitions. |
| ESD Protection | HBM: 2kV, CDM: 1kV - meets IEC 61000-4-2 Level 2 requirements for handheld device front-end robustness. |
Pinout & Package
AP22916CCA4-7 is housed in a wafer-level chip-scale package: U-WLB0808-4 (Type B), measuring 0.78mm × 0.78mm × 0.455mm with 0.4mm ball pitch and backside laminate construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT (A1) | Switch output node / P-MOSFET drain | Connects to load; requires local 0.1µF–1µF bypass capacitor to GND for transient stability and EMI suppression. |
| VIN (A2) | Switch input node / P-MOSFET source | Connects to power rail; requires 1µF ceramic decoupling capacitor placed adjacent to minimize input impedance spikes. |
| GND (B1) | Power and signal reference | Low-impedance return path for load current and internal logic; must be tied directly to system ground plane with minimal trace inductance. |
| ON (B2) | Active-high enable control input | Drives internal gate driver; internal 750kΩ pull-down ensures safe OFF state during MCU reset or unpowered states. |
Key Features
| Feature | Design Value |
|---|---|
| True Reverse Current Blocking (TRCB) | Blocks reverse current flow when VOUT > VIN + 25mV, protecting upstream supplies from backfeed in multi-source systems. |
| Ultra-Low Quiescent Current | 0.5µA typical - extends battery life in always-on wearable sensors and low-power IoT endpoints. |
| Controlled Turn-On Timing | 1400µs tON at 5V (AP22916C variant) - prevents inrush-induced voltage droop on shared rails during hot-plug events. |
| Integrated Output Discharge | 150Ω on-chip resistor - eliminates need for external bleed circuitry, reducing BOM count and PCB area in compact designs. |
| Smart Pull-Down on ON Pin | 750kΩ internal resistor - guarantees default-OFF behavior without external components, simplifying GPIO interface design. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar load-switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP22916BAA4-7 | Faster turn-on (85µs vs. 1400µs), same TRCB and package - optimized for high-speed rail switching, not inrush-limited loads. | Suitable for dynamic core voltage scaling where rapid rail enable/disable is required; unsuitable for large-capacitance loads without external inrush limiting. | Select AP22916BAA4-7 only when tON < 200µs is mandatory and inrush current is managed elsewhere in the design. |
| TCK107AG,LF | Lower RDS(ON) (25mΩ @ 5V), no TRCB, higher IQ (1.2µA), same 2A rating and 1.3–5.5V range. | Lacks reverse-current protection - requires external diode or circuitry for backfeed prevention; better for cost-sensitive consumer wearables without multi-rail interaction. | Choose TCK107AG,LF only when TRCB is unnecessary and lowest possible conduction loss is prioritized over reverse protection and ultra-low IQ. |
Compared with AP22916BAA4-7 and TCK107AG,LF, the AP22916CCA4-7 uniquely balances ultra-low IQ (0.5µA), guaranteed TRCB (25mV/10μs), and controlled turn-on (1.4ms) - making it optimal for battery-critical, multi-rail portable systems where reliability and inrush safety outweigh raw speed or RDS(ON) minimization.

FAQ
What is the maximum continuous load current supported by AP22916CCA4-7?
The AP22916CCA4-7 supports up to 2A continuous load current across its full operating temperature range (–40°C to +85°C). This rating assumes proper PCB thermal design with adequate copper area and ambient temperature ≤ 60°C. At elevated temperatures or with limited heatsinking, derating applies per the 195°C/W RθJA specification.
Does AP22916CCA4-7 require an external pull-up resistor on the ON pin?
No. The AP22916CCA4-7 integrates a 750kΩ internal pull-down resistor on the ON pin, ensuring a defined OFF state during power-up, reset, or unconnected GPIO conditions. An external pull-up is unnecessary unless a specific logic polarity inversion or noise immunity enhancement is required in the system design.
How does True Reverse Current Blocking (TRCB) function when the device is disabled?
TRCB remains fully active even when the AP22916CCA4-7 is disabled (ON = low). If VOUT rises above VIN by more than 25mV, the internal comparator immediately disables the P-MOSFET channel and sinks reverse current up to –650mA, preventing backfeed into the input rail regardless of ON pin state.
Can AP22916CCA4-7 be used with input voltages below 1.3V?
No. The absolute minimum recommended input voltage is 1.3V per the datasheet's Recommended Operating Conditions. Operation below this voltage risks undefined behavior, including failure to turn on reliably or increased RDS(ON). At 1.3V, RDS(ON) is 280mΩ typical - sufficient only for ≤500mA loads under tight thermal constraints.
