Overview
The PM8834MTR, produced by STMicroelectronics, is a flexible, high-frequency dual low-side MOSFET driver designed to work with high capacitive MOSFETs and IGBTs. This device is part of the PM8834 family and is specifically packaged in a MINI SO8 package with an exposed pad. It is capable of sinking and sourcing 4 A independently on each output, with the option to parallel the outputs to achieve higher driving currents up to 8 A. The PM8834MTR operates with CMOS/TTL-compatible PWM signals and features independent enable pins for each driver, allowing for precise control over the operation of each output line.
