Description
A89500 100 V Half-Bridge MOSFET Driver FEATURES AND BENEFITS Half-bridge MOSFET driver AEC-Q100 qualified (K version) Suitable for 12 V, 24 V, and 48 V power networks Operates with up to 100 V bridge supply 8 to 15 V supply voltage Bootstrap gate drive for N-channel MOSFET bridge Cross-conduction protection Individual MOSFET control Low-power sleep mode Supply undervoltage lockout PACKAGE: Not to scale 10-lead DFN with wettable flank and exposed pad (suffix EJ) DESCRIPTION TheA89500 is an N-channel power MOSFET driver capable of controlling MOSFETs connected in a half-bridge arrangement with up to 100 V bridge supply. It is specifically designed for applications with high-power inductive loads, such as brush DC motors, solenoids, and actuators and is compatible with 12 V, 24 V, and 48 V power networks. Internal logic prevents the gate drive outputs from turning on at the same time, preventing cross-conduction. Each MOSFET is controlled by an independent logic-level input compatible with 3.3 V and 5 V logic. The A89500 can be placed in a low-power sleep mode by a third discrete input. It requires a single 8 to 15 V supply to power the gate drivers. The A89500 is supplied in a 10-lead DFN (suffix EJ) with wettable flank and exposed thermal pad. This package is lead (Pb) free, with 100% matte-tin leadframe plating.
