**analogysemi** · Current Sense Amplifiers · SOT-23-5

CSA230PASOT235 from analogysemi, in a SOT-23-5. 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 | GND | power_in | Ground reference for the device. |
| 2 | OUT | output | Analog output of the current sense amplifier; output voltage range from VOL (no load: 4 mV, sink 500 µA: 15 mV) to VOH (source 500 µA: VDD - 0.015 V). |
| 3 | VDD | power_in | Power supply voltage (2.7 V to 5.5 V); connect at least 100 nF bypass capacitor to GND. |
| 4 | RS- | input | External sense resistor load-side connection; input voltage range 0 V to 76 V with respect to GND. |
| 5 | RS+ | input | External sense resistor power-side connection; input voltage range 0 V to 76 V with respect to GND. |
