AP22652/AP22653/AP22652A/AP22653A
PRECISION ADJUSTABLE CURRENT-LIMITED POWER SWITCHES Description Pin Assignments 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. (Top View) EN/EN
W-DFN2020-6 (Type A1)
(Top View) 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, over-temperature and short-circuit protection, as well as
controlled rise time and under-voltage lockout functionality. A
6ms deglitch capability on the open-drain Flag output prevents false
over-current reporting and does not require any external components. IN 1 6 OUT GND 2 5 ILIM EN/EN

The AP22652 and AP22653 limit the output current to a safe level
when the output current exceeds current-limit threshold. Features The AP22652A and AP22653A provide latch-off function during overcurrent or reverse-voltage conditions. Up to 2.1A Maximum Load Current
