AP2141DSG-13

Diodes Incorporated · AC-DC Controllers and Regulators · SO-8

AP2141DSG-13 from Diodes Incorporated, in a SO-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT power_out Switched voltage output pin from the internal high-side power MOSFET. Delivers up to 0.5 A recommended continuous load with ~95 mΩ typical on-resistance at Vin = 5 V. When the switch is disabled, an internal discharge path (~100 Ω) sinks residual output charge to GND.
2 GND power_in Device ground reference. All internal analog and control circuitry are referenced to this pin.
3 FLG output Open-drain fault flag output, active low when an over-current or over-temperature event exceeds the 7 ms typical blanking time. FLG FET has ~20 Ω on-resistance at 10 mA sink; requires an external pull-up resistor (typ 10 kΩ) to a logic supply up to 6.5 V.
4 EN input Enable input, active LOW on AP2141D (drive low to turn the switch on). Logic thresholds: VIL ≤ 0.8 V, VIH ≥ 2.0 V. Input leakage ≤1 µA at VEN = 5 V. Absolute max VEN = 6.5 V.
5 IN power_in Voltage input supply pin to the internal power MOSFET and control circuitry. Operating range 2.7 V to 5.5 V; UVLO trip ~1.9 V typical. Absolute max VIN = 6.5 V. Bypass locally with ceramic (0.1 µF) and bulk (10 µF) capacitors.
