Overview
UC1725 UC2725 UC3725 Isolated High Side FET Driver FEATURES • • • • • Receives Both Power and Signal Across the Isolation Boundary 9 to 15 Volt High Level Gate Drive Under-voltage Lockout Programmable Over-current Shutdown and Restart Output Enable Function DESCRIPTION The UC1725 and its companion chip, the UC1724, provide all the necessary features to drive an isolated MOSFET transistor from a TTL input signal.
A unique modulation scheme is used to transmit both power and signals across an isolation boundary with a minimum of external components.
Protection circuitry, including under-voltage lockout, over-current shutdown, and gate voltage clamping provide fault protection for the MOSFET.
