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
(Top View)
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 EN/EN 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.
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 IN 1 6 OUT applications subject to heavy capacitive loads and the prospect of short circuit, offering reverse current blocking and limiting, over- GND 2 5 ILIM current, 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 EN/EN EN 3 4 FAULT over-current reporting and does not require any external components.
SOT26 (Type A1)
The AP22652 and AP22653 limit the output current to a safe level
Features
when the output current exceeds current-limit threshold. Up to 2.1A Maximum Load Current The AP22652A and AP22653A provide latch-off function during over- Accurate Adjustable Current Limit, 125mA to 2665mA current or reverse-voltage conditions. ±7% Accurate Adjustable Current Limit, 1.735A with RLIM = 15kΩ Constant-Current (AP22652/53) During Over-Current All devices are available in SOT26 (Type A1) and W-DFN2020-6 Output Latch-Off (AP22652A/53A) at Over-Current (Type A1) packages. Fast Short-Circuit Response Time: 5µs (typ) Reverse Current Blocking During Shutdown and Reverse Current
