ACPL-K370, Isolated Voltage/Current Detector

The ACPL-K370 and ACPL-K376 are voltage/current threshold detection optocouplers.

The ACPL-K376 is a lowcurrent version of the ACPL-K370.

To obtain lower current operation, the ACPL-K376 uses a high-efficiency AlGaAs LED which has higher light output at lower drive currents.

Both devices have a thre

ACPL-K370 Features

* hysteresis for extra noise immunity and switching immunity, a diode bridge for easy use with AC input signals, and internal clamping diodes to protect the buffer and LED from over-voltage and over-current transients. Because threshold sensing is done prior to driving the LED, variations in optical
