Overview
ACPL-K370, ACPL-K376 Isolated Voltage/Current Detector Data Sheet Description 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 threshold sensing input buffer IC that allows threshold levels to be set by a single external resistor over a wide range of input voltages.
The input buffer has several performance enhancing 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 coupling from the LED to the detector will not effect the threshold levels.
The ACPL-K370 input buffer IC has a nominal turn-...
