UC3825 General Description

In addition, the UC3825 incorporates an under-voltage lockout mechanism with 800mV of hysteresis, guaranteeing a safe start-up process and minimizing current draw during initial operation. During under-voltage lockout, the outputs are switched to high impedance mode, providing an added layer of protection

Key Features

Under-Voltage Lockout with Hysteresis
Pulse-by-Pulse Overcurrent Protection up to 3A
Dual Outputs with Independent Shutdowns and Enable
Fault-Tolerant Operation up to 1.5 Failures
Soft Start / Max. Duty Cycle Control up to 2kHz
Automatic Recovery from Transient Faults up to 50V
