HT0440中文资料Dual, High Voltage, Isolated MOSFET Driver数据手册Microchip规格书

描述 Description

HT0440 is a dual, high voltage, isolated MOSFET driver utilizing proprietary HVCMOS® technology. It is designed to drive discrete MOSFETs configured as bidirectional or unidirectional switches. It can drive N-channel MOSFETs as high-side switches up to 400V. The HT0440 generates two independent DC isolated voltages to the outputs, VOUTA and VOUTB when logic inputs A and B are at logic high. The internal clock of the HT0440 can be disabled by applying an external clock signal to the CLK pin. This allows the power dissipation and AC characteristics to be tailored to meet specific needs. The CLK pin should be connected to ground when not in use. The HT0440 does not require any external power supplies, the internal supply voltage is supplied by either of the two logic inputs, A or B, when they are at logic high.For detailed circuit application information, please refer to application note AN-D26.
