The BTN7963B is part of the NovalithIC™ family containing three separate chips in one package: One p-channel
highside MOSFET and one n-channel lowside MOSFET together with a driver IC, forming an integrated high
current half-bridge. All three chips are mounted on one common lead frame, using the chip on chip and chip by
chip technology. The power switches utilize vertical MOS technologies to ensure optimum on state resistance.
Due to the p-channel highside switch the need for a charge pump is eliminated thus minimizing EMI. Interfacing
to a microcontroller is made easy by the integrated driver IC which features logic level inputs, diagnosis with
current sense, slew rate adjustment, dead time generation, smart clamping in overvoltage and protection against
overtemperature, undervoltage, overcurrent and short circuit. The BTN7963B can be combined with other
BTN7963B to form H-bridge and 3-phase drive configurations.
