**Diodes Incorporated** · Current Sense Amplifiers · SOT-23-5

ZXCT1041E5TA from Diodes Incorporated, 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 | Flag | output | Current direction flag output. Open-collector; requires an external pull-up (can be tied to a rail independent of VS+). Low indicates VS+ > VS- (forward current); Flag trip point referred to VSENSE is ±2.5mV. VOL ≤ 200mV at ISINK = 100µA; leakage ≤ 1µA at VOH = 5V. |
| 2 | GND | power_in | Ground reference pin for the device. Ground pin quiescent current (IQ) is typically 35µA (15µA min, 50µA max). |
| 3 | OUT | output | Analog output voltage pin. VOUT = 10 × VSENSE (gain of 10 V/V). Output swing is 0V to (VS± − 1.5V); designed for VSENSE in the 50mV-150mV range. Bandwidth ~300kHz. |
| 4 | S+ | power_in | Positive sense input and device supply pin. Provides current for internal circuitry; input current varies with differential sense voltage (IS+ typ 17µA at VSENSE = 0V). Common-mode range 2.7V to 20V; absolute max −0.6V to +20V. |
| 5 | S- | input | Negative sense input of the current monitor. Connected to the load side of the external sense resistor RS. Input current varies with differential sense voltage (IS- typ 17µA at VSENSE = 0V). Differential VSENSE = (VS+) − (VS-), rated ±0.8V operating, ±6V absolute max. |
