Allegro MicroSystems AMT49502 Half-Bridge MOSFET Driver
Allegro MicroSystems AMT49502 Half-Bridge MOSFET Driver is an 80V-rated gate driver that can operate in both 12V/48V systems with a 5.5V to 80V operational rating. This MOSFET driver is designed specifically for driving N-channel MOSFETs in half-bridge configurations, which is essential for controlling DC motors, solenoids, and other inductive loads. The AMT49502 driver offers advanced diagnostics and verification features, allowing customers to develop solutions with a common software and PCB footprint for both 12V and 48V systems. This half-bridge driver comes in a 24-lead eTSSOP package that is well-suited for automotive and industrial applications due to its robust design and integrated protection features.
The AMT49502 N-channel power MOSFET driver provides detailed diagnostics and flexible I/O voltage compatibility to simplify integration and ASIL compliance. This driver is targeted at high-efficiency starter generator applications, high-performance actuators, and automotive applications with high-power inductive loads, like BLDC motors, VR/SR motors, and solenoids.
