ZXSC310E5TA

Diodes Incorporated · LED Drivers · TSOT-23-5

ZXSC310E5TA from Diodes Incorporated, in a TSOT-23-5. 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 VCC power_in Supply voltage pin, recommended range 0.8 V to 8 V, with absolute maximum supply of 10 V, generally a single Alkaline, NiMH or NiCd cell.
2 Gnd power_in Ground reference pin for the device.
3 STDN input Shutdown control input where the device is enabled at 0.7 V or higher and in standby at 0.15 V or lower, and it is enabled if left open circuit.
4 ISENSE input Inductor current sense input with an internal threshold of 19 mV (14 mV to 24 mV), connected to an external sense resistor in series with the switching transistor emitter.
5 VDRIVE output Drive output for the external switching transistor, connected to its base, with a high level of VCC minus 0.3 V minimum and a low level of 0.2 V maximum.
