Summary of DIODES INCORPORATED AP22653Q PRECISION-ADJUSTABLE POWER SWITCHES
The AP22653Q is a precision-adjustable power switch providing protection for heavy capacitive loads and short-circuit conditions. It offers adjustable current limiting, reverse-current blocking/limiting, fast short-circuit response, overcurrent/overtemperature protection, controlled soft-start, under-voltage lockout, and a de-glitched open-drain fault output. Available in SOT26, it supports 3.0–5.5V operation, up to 1.5A load (adjustable to ~1.735A), includes ESD protections, and is AEC-Q100 qualified and RoHS compliant.
Parts used in the AP22653Q Precision-Adjustable Power Switches Project:
- AP22653Q device (SOT26 package)
- RLIM resistor (to set adjustable current limit)
- Decoupling capacitors for supply stability
- Load (capacitive or resistive as application dependent)
- Microcontroller or enable control source (for Enable active high)
- PCB with appropriate thermal and layout considerations
- ESD protection components or recommended external capacitance for IEC61000-4-2 testing
The AP22653Q provides 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, short-circuit protection, as well as controlled rise-time and under-voltage lockout functionality.
A 6ms de-glitch capability on the open-drain flag output prevents false overcurrent reporting and does not require any external components. The AP22653Q limits the output current to a safe level when the output current exceeds the current-limit threshold.
The Diodes Inc AP22653Q Precision-Adjustable Power Switches have a fast short-circuit response time for improved overall system robustness and are available in the SOT26 (Type A1) package.
