CSA230MASOT235

analogysemi · Current Sense Amplifiers · SOT23-5

CSA230MASOT235 from analogysemi, in a SOT23-5. 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 GND power_in Power ground connection of the device, the reference for VDD and the other pins.
2 OUT output Output pin, which sits within 10mV of GND when sinking 500µA and within 0.01V of VDD when sourcing 500µA (Table 8).
3 VDD power_in Power supply input operating from 2.7V to 5.5V (Table 6), with at least a 100nF capacitor connected to GND.
4 RS- input External sense-resistor load-side connection, with input common-mode range of 0V to 76V and an absolute maximum of -0.3V to 80V to GND.
5 RS+ input External sense-resistor power-side connection, with input common-mode range of 0V to 76V and an absolute maximum of -0.3V to 80V to GND.
