Integrated 3-Channel high voltage, High-speed power MOSFET and IGBT gate

driver, Suitable for applications up to 60V with very low power consumption.

All three channels have under-voltage lockout functions. All logic are powered

by an internal 5V LDO, the output of LDO can also supply to external circuits

up to 50mA capability. A ground-reference operational amplifier provides

amplifications of bridge current via external current sense resistor. It also has

built-in comparator for over-current protection.
