The Broadcom ACPL-K376 is voltage/current threshold detection opt couplers. The ACPL-K376 is a low current 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.
± 5% voltage detection accuracy Wide AC or DC detection range up to 1140 Vpeak User configurable single/dual detection levels Built-in hysteresis improves noise immunity Very low threshold current 132 mA (ACPL-K376) Logic compatible output Wide output supply voltage 2 V to 18 V –40°C to +105°C operating temperature range SSO-8 package with 8 mm creepage and clearance
