AP2553A - PRECISION ADJUSTABLE CURRENT-LIMITED POWER SWITCHES

Download the AP2553A datasheet PDF. This datasheet also covers the AP2552 variant, as both devices belong to the same precision adjustable current-limited power switches family and are provided as variant models within a single manufacturer datasheet.

Description

The AP2552/53 and AP2552A/53A 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.

Features

  • Up to 2.1A Maximum Load Current.
  • Accurate Adjustable Current Limit, 75mA to 2365mA.
  • ±6% Accurate Adjustable Current Limit, 1.632A with RLIM = 15kΩ.
  • Constant-Current (AP2552/53) During Over-Current.
  • Output Latch-Off (AP2552A/53A) at Over-Current.
  • Fast Short-Circuit Response Time: 2µs (Typ. ).
  • Reverse Current Blocking During Shutdown and Reverse Current Limiting During Enable.
  • Operating Range: 2.7V to 5.5V.
  • Built-in S.

NOT RECOMMENDED FOR NEW DESIGN USE AP22652/AP22653/AP22652A/AP22653A AP2552/AP2553 AP2552A/AP2553A PRECISION ADJUSTABLE CURRENT-LIMITED POWER SWITCHES Description The AP2552/53 and AP2552A/53A 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 75mA and 2.36A (Typ.) via an external resistor. Current limit accuracy ±6% can be achieved at high current-limit settings. The rise and fall time are controlled to minimize current surges during turn on/off. The devices have fast short-circuit response time for improved overall system robustness.
