PM8834 4 A dual low-side MOSFET driver Datasheet - production data Applications SMPS DC-DC converters Motor controllers Line drivers Class-D switching amplifiers Description The PM8834 is a flexible, high-frequency dual Features low-side driver specifically designed to work with high capacitive MOSFETs and IGBTs. Dual independent low-side MOSFET driver with 4 A sink and source capability Both PM8834 outputs can sink and source 4 A Independent enable for each driver independently. A higher driving current can be obtained by connecting the two PWM outputs in Driver output parallelability to support higher parallel. driving capability The PM8834 provides two enable pins which can Matched propagation delays be used to enable the operation of one or both of CMOS/TTL-compatible input levels the output lines. Wide input supply voltage range: 5 V to 18 V The PM8834 works with a CMOS/TTL-compatible Embedded drivers with anti cross conduction PWM signal. protection The device is available in an SO8 or an MSOP8 Low bias switching current package with an exposed pad. Short propagation delays Rated for a wide operative temperature range: -40 C to 125 C Industry standard SO8 package and MSOP8 with exposed pad Table 1.
