UC2725 General 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.High level gate drive is guaranteed to be greater than 9 volts and less than 15 volts under all conditions.
Uses include isolated off-line full bridge and half bridge drives for driving motors, switches, and any other load requiring full electrical isolation.
The UC1725 is characterized for operation over the full military temperature range of -55°C to +125°C while the UC2725 and UC3725 are characterized for -25°C to +85°C and 0°C to +70°C respectively.
