Diodes Incorporated AP22913CN4-EVM

Overview

AP22913CN4-EVM from Diodes Incorporated is an evaluation board for the AP22913 single-channel, slew-rate-controlled P-channel load switch in X1-WLB0909-4 (WLCSP-4) package. It supports 1.4V–5.5V input, delivers up to 2A continuous load current, features true reverse current blocking (TRCB), and demonstrates controlled turn-on with <1µA quiescent current-used for validating high-side power sequencing in portable electronics.

For engineers reviewing the AP22913CN4-EVM datasheet, AP22913CN4-EVM pinout, AP22913CN4-EVM application, or AP22913CN4-EVM equivalent, this board enables rapid characterization of load-switch timing, R_DS(ON) behavior at 1.8V/3.3V/5V, TRCB effectiveness under reverse bias, and thermal performance under pulsed 2.5A loads.

Technical Context

The AP22913CN4-EVM implements a fixed-layout demonstration of the AP22913 load switch in its native WLCSP-4 footprint, with VIN, VOUT, ON, and GND brought out to test points and solder jumpers. It integrates 1µF input and 0.1µF output ceramic capacitors per recommended layout, plus a 10kΩ pull-up resistor for ON control.

This EVM operates across the full AP22913 input range (1.4V–5.5V), supports load currents up to 2A DC or 2.5A pulsed (300µs, 2% duty), and allows direct probing of VON-to-VOUT slew rate, output discharge behavior during disable, and reverse leakage under TRCB conditions.

FAQ

What is the purpose of the J1 jumper on the AP22913CN4-EVM?

J1 provides a hardware-selectable ON pin default state: shorting pins 1–2 sets ON = VIN (always enabled), while shorting pins 2–3 sets ON = GND (always disabled). This allows quick functional verification without external control signals, matching common system-level enable logic configurations.

Can the AP22913CN4-EVM be used to measure R_DS(ON) at different input voltages?

Yes - the board exposes VIN, VOUT, and load return paths via test points, enabling direct four-wire Kelvin measurement of voltage drop across the AP22913 MOSFET under controlled 1.4V–5.5V input and 0–2A load conditions, as validated in the datasheet's R_DS(ON) vs. V_IN curves.

Does the AP22913CN4-EVM include reverse-current blocking validation circuitry?

Yes - the board's layout isolates VIN and VOUT with no shared passive components between rails, allowing direct measurement of reverse leakage current when VOUT > VIN. The AP22913's TRCB feature blocks >99.9% of reverse current, confirmed by applying 5V to VOUT while VIN = 0V and measuring sub-100nA leakage.

Is the AP22913CN4-EVM RoHS-compliant and halogen-free?

Yes - the board uses only RoHS 3-compliant (2015/863/EU) and halogen-free components, including the AP22913CCN4-7 IC (Br/Cl <900ppm each, Sb <1000ppm), Taiyo Yuden MLCCs, and Yageo resistors, consistent with Diodes Incorporated's green manufacturing standards.
