Product details
Overview
AP22916BCA4-7 from Diodes Incorporated is a single-channel, P-channel ultra-low leakage load switch IC designed for power sequencing and battery-powered system rail control. 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 mobile device power rails to isolate peripherals during sleep mode.
For engineers reviewing the AP22916BCA4-7 datasheet, AP22916BCA4-7 pinout, AP22916BCA4-7 application, or AP22916BCA4-7 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 fast turn-on timing (85μs typ. at 5V).
Technical Context
The AP22916BCA4-7 implements a smart P-MOSFET load switch with integrated driver logic, TRCB comparator, and output discharge resistor. Its ON pin includes a built-in smart pull-down (750kΩ typical) that ensures reliable disable state without external components.
TRCB activates when VOUT exceeds VIN by ≥25mV, blocking reverse current within 10μs while maintaining isolation even during shutdown. The device supports multiple input voltages (1.3V–5.5V) with RDS(ON) scaling from 280mΩ @1.3V to 54mΩ @5.0V, enabling consistent performance across low-voltage portable systems.
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 level-shifting. |
| RDS(ON) @5V | 54mΩ typical - enables 2A continuous load with ≤108mV conduction loss, minimizing thermal rise in compact layouts. |
| Quiescent Current | 0.5µA typical - reduces standby power drain in always-on subsystems such as real-time clocks or sensor hubs. |
| TRCB Trigger Threshold | 25mV - detects minor backfeed conditions early, preventing battery drain or supply contamination from downstream sources. |
| Turn-On Time @5V | 85μs typical - provides controlled power ramp for noise-sensitive analog or RF circuits during wake-up sequences. |
| Output Discharge | Enabled - discharges VOUT via internal resistor when disabled, eliminating floating voltage and enabling safe hot-swap operation. |
| ESD Protection | HBM: 2kV, CDM: 1kV - meets IEC 61000-4-2 Level 2 requirements for handheld and wearable end-equipment handling. |
Pinout & Package
AP22916BCA4-7 is housed in a wafer-level chip-scale U-WLB0808-4 (Type B) package: 0.78mm × 0.78mm × 0.455mm footprint, 0.4mm ball pitch, with backside laminate construction for thermal and mechanical robustness in space-constrained designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT (A1) | P-channel MOSFET drain | Switched output node; requires local 0.1µF–1µF bypass capacitor to GND for transient stability. |
| VIN (A2) | P-channel MOSFET source | Main input supply connection; requires 1µF ceramic decoupling capacitor placed adjacent to pin. |
| GND (B1) | Power ground reference | Low-impedance return path for load current and internal logic; must connect to solid ground plane. |
| ON (B2) | Active-high enable control | Logic input with 1.0V VIH min; internal 750kΩ pull-down ensures fail-safe OFF state if left un-driven. |
Key Features
| Feature | Design Value |
|---|---|
| True Reverse Current Blocking (TRCB) | Blocks reverse current within 10μs when VOUT > VIN + 25mV - prevents back-powering of upstream supplies in multi-rail systems. |
| Ultra-Low Quiescent Current | 0.5µA typical - extends battery life in always-on subsystems without compromising switch responsiveness. |
| Integrated Output Discharge | Active during disable - eliminates residual VOUT voltage, enabling safe reconfiguration and avoiding latch-up in downstream ICs. |
| Wide Input Voltage Compatibility | 1.3V–5.5V operation - eliminates need for separate load switches per voltage domain in mixed-supply portable devices. |
| Smart Pull-Down on ON Pin | 750kΩ internal resistor - removes requirement for external pull-down, simplifying layout and reducing BOM count. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar load-switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP22916CCA4-7 | Slower turn-on (1400μs typ. @5V), same TRCB and discharge features | Better suited for inrush-limited applications like LED drivers where soft-start is required | Select for reduced EMI or when slower ramp rate avoids supply droop on weak sources |
| TPL7407LDR | 7-channel N-MOS array, no TRCB, higher IQ (2.5µA), 150mΩ RDS(ON) | Targeted at GPIO-expansion-based switching, not single-rail isolation | Choose only when multi-load control is needed and TRCB is unnecessary |
Compared with AP22916BCA4-7, the AP22916CCA4-7 trades speed for lower inrush stress, while TPL7407LDR offers channel density at the cost of reverse-blocking capability and higher leakage-making AP22916BCA4-7 optimal for single-rail, battery-critical, TRCB-required use cases.

FAQ
What is the maximum continuous load current supported by AP22916BCA4-7?
The AP22916BCA4-7 supports up to 2A continuous load current at ambient temperatures from –40°C to +85°C, provided thermal design limits junction temperature to ≤125°C. At 1.3V input, max continuous current is derated to 1.0A per datasheet specifications under recommended operating conditions.
Does AP22916BCA4-7 require an external pull-down resistor on the ON pin?
No. The AP22916BCA4-7 integrates a 750kΩ smart pull-down resistor on the ON pin, ensuring automatic disable when the control signal is floating or undriven. This eliminates the need for external components and improves board-level reliability in noisy environments.
How does True Reverse Current Blocking (TRCB) operate when the device is disabled?
TRCB remains fully active regardless of ON pin state. When VOUT exceeds VIN by ≥25mV, the internal comparator disables the P-MOSFET within 10μs-even during shutdown-preventing reverse current flow from output to input and protecting upstream power sources.
Can AP22916BCA4-7 be used with 1.3V logic-level microcontrollers?
Yes. With a VIH threshold of only 1.0V, the AP22916BCA4-7 is compatible with 1.3V, 1.8V, and higher logic families. Its ON pin accepts standard CMOS-compatible signals, and the 0.5µA quiescent current ensures minimal loading on low-power MCU GPIOs.
