Product overview
Description
The PM7050A is a smart device that integrates a high-side and low-side MOSFET, and a high performance driver with integrated bootstrap FET. The PM7050A offers high accuracy current and temperature monitors that can be provided to the controller of a multiphase DC/DC system. They simplify design and increase performance by eliminating the DCR sensing network and associated thermal compensation. An industry leading, thermally enhanced, 4 x 5 mm package allows minimal overall PCB real estate and low profile construction.
The device features a 3.3 V compatible tri-state PWM input that, together with multiphase controllers, provides a robust solution in the event of abnormal operating conditions. The PM7050A also integrates UVLO monitoring and fault protections such as overtemperature, overcurrent and HS MOSFET short failures.
