UTC Unisonic Tech · Comparators · SOT-25-5

TS391CG-AF5-R from UTC Unisonic Tech, in a SOT-25-5. 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 IN(-) input Inverting comparator input. Common-mode voltage range includes ground: 0V to VCC-1.5V at TA=+25°C. Differential input voltage may equal supply voltage; low-side input must not go below -0.3V.
2 GND power_in Ground / negative supply reference. All voltages are referenced to this pin.
3 IN(+) input Non-inverting comparator input. Common-mode voltage range includes ground: 0V to VCC-1.5V at TA=+25°C. Input bias current 25nA typ, offset current ±5nA typ.
4 Output output Open-collector comparator output. Requires external pull-up to VCC (or other voltage up to +36V). Low-level output voltage 250mV typ at IOUT=4mA; sink current 6mA min at VOUT=1.5V; maximum output current ~20mA.
5 VCC power_in Positive supply pin. Single-supply range +2V to +36V, or ±1V to ±18V split supply. Supply current 0.2mA typ at VCC=5V (no load), 0.5mA typ at VCC=30V.
