Description

The PM8834 is a flexible, high-frequency dual

low-side driver specifically designed to work with

high capacitive MOSFETs and IGBTs.

Both PM8834 outputs can sink and source 4 A

independently. A higher driving current can be

obtained by connecting the two PWM outputs in

parallel.

The PM8834 provides two enable pins which can

be used to enable the operation of one or both of

the output lines.

The PM8834 works with a CMOS/TTL-compatible

PWM signal.

The device is available in an SO8 or an MSOP8

package with an exposed pad.
