AP22652/AP22653/AP22652A/AP22653A

PRECISION ADJUSTABLE CURRENT-LIMITED POWER SWITCHES

Description

The AP22652, AP22653, AP22652A, and AP22653A are single-

channel, precision-adjustable, current-limited switches optimized for

applications that require precision current limiting, or to provide up to

2.1A of continuous load current during heavy loads/short circuits.

These devices offer a programmable current-limit threshold between

125mA and 2665mA (typ) via an external resistor. Current-limit

accuracy ±10% can be achieved at high current-limit settings. The

rise and fall times are controlled to minimize current surges during

turn on/off.

The devices have fast short-circuit response time for improved overall

system robustness. They provide a complete protection solution for

applications subject to heavy capacitive loads and the prospect of

short circuit, offering reverse-current blocking and limiting,

overcurrent, overtemperature, and short-circuit protection, as well as

controlled rise time and undervoltage lockout functionality. A 6ms

deglitch capability on the open-drain flag output prevents false

overcurrent reporting and does not require any external components.

The AP22652 and AP22653 limit the output current to a safe level

when the output current exceeds current-limit threshold.

The AP22652A and AP22653A provide latch-off function during

overcurrent or reverse-voltage conditions.

All devices are available in SOT26 (Type A1) and W-DFN2020-6

(Type A1) packages.
