HUSB601_ASA

Hynetek · Battery Management · SOT23-6L

HUSB601_ASA from Hynetek, in a SOT23-6L. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 DP bidirectional USB D+ line, connected directly to the D+ pin of the USB connector; the DP pin is rated from -0.3 V to +25 V.
2 GND power_in Ground reference, connected to the system ground.
3 FB bidirectional Feedback control pin, connected to the feedback node of the power system; it sources or sinks current in 0.2 µA LSB steps with an output voltage range of 0.4 V to 2.5 V, and its absolute maximum rating is -0.3 V to +6.5 V.
4 SEL input Maximum charging voltage selection input: High (pulled up to VCC) selects 12 V, Floating selects 9 V, and Low selects 5 V for HUSB601_ASA, with input low threshold 0.3 V and input high threshold 2.2 V to VCC.
5 VCC power_in Supply input, decoupled to GND with a 1 µF ceramic capacitor and connected to the power system output through a 2 kΩ resistor; the input voltage range is 2.9 V to 5.5 V and the absolute maximum rating is -0.3 V to +6.5 V.
6 DM bidirectional USB D- line, connected directly to the D- pin of the USB connector; the DM pin is rated from -0.3 V to +25 V.
