Diodes Incorporated AP22913CN4-7

Overview

AP22913CN4-7 from Diodes Incorporated is a single-channel, slew-rate-controlled, high-side P-channel MOSFET load switch with True Reverse Current Blocking (TRCB), designed for power domain isolation in portable electronics. It operates from 1.4V to 5.5V input, delivers up to 2A continuous load current, features 54mΩ typical R_DS(on) at 5V in the X1-WLB0909-4 package, and consumes only 1µA quiescent current - enabling efficient battery-powered operation in space-constrained designs.

For engineers reviewing the AP22913CN4-7 datasheet, AP22913CN4-7 pinout, AP22913CN4-7 application, or AP22913CN4-7 equivalent, key selection considerations include its controlled turn-on slew rate (720µs typ @5V), TRCB threshold (44mV), ultra-low shutdown leakage (<0.1µA), and dual-package availability (WLB0909-4 and SOT26) for thermal and layout flexibility.

Technical Context

The AP22913 integrates an internal slew-rate control circuit that limits dV/dt on VOUT during turn-on to suppress inrush current and reduce EMI. Its TRCB function uses a precision comparator to detect reverse voltage (V_OUT − V_IN > 44mV) and disable the P-MOSFET within 10µs, preventing backfeed even when disabled.

It includes an integrated discharge FET (R_DIS = 150–200Ω) that actively pulls VOUT to GND upon disable, eliminating floating outputs. The active-high ON pin requires only 1.1V VIH, supporting direct interface with low-voltage logic (1.8V/2.5V I/O), and UVLO ensures reliable turn-off below 1.2V input.

FAQ

What is the maximum continuous load current supported by AP22913CN4-7?

The AP22913CN4-7 supports up to 2A continuous load current at ambient temperatures ≤+85°C with proper PCB copper pour and thermal relief. Derating applies above +85°C per its 136°C/W junction-to-ambient thermal resistance; at 2A and 5V input, power dissipation is ~216mW, resulting in ~30°C junction rise above ambient under typical layout conditions.

Does AP22913CN4-7 require an external pull-up resistor on the ON pin?

No. The ON pin has no internal pull-up; however, its 1.1V minimum VIH and 0.4V/0.6V VIL thresholds allow direct connection to 1.8V or higher GPIO without external components. If driven by open-drain logic or weak sources, a 100kΩ pull-up to VIN is recommended to ensure reliable turn-on.

How does the TRCB feature behave when the AP22913CN4-7 is disabled?

TRCB remains fully active even when the device is disabled (ON = low). If V_OUT exceeds V_IN by more than 44mV, the internal comparator immediately disables the P-MOSFET channel, blocking reverse current flow regardless of ON pin state - providing fail-safe protection during system-level fault conditions.

Can AP22913CN4-7 be used with output capacitance larger than 1µF?

Yes. While 0.1–1µF is recommended for optimal slew control, larger output capacitance (e.g., 10µF) is supported and shown in the datasheet's performance curves. Increasing C_OUT further slows turn-on (e.g., 2300µs @1.5V/10µF) but enhances transient suppression; layout must maintain short, wide traces to minimize parasitic inductance.
