#HALF BRIDGE MOSFET DRIVER DRIVER#
It is a single chip half bridge gate driver for the N-channel power MOSFET. In addition to providing full access to the bridge control, the serial interface is also used to alter programmable settings such as dead time, VDS threshold, and fault blank time. The L6393 is a high voltage device manufactured with the BCD offline technology.

Integrated diagnostics provide indication of multiple internal faults, system faults, and power bridge faults, and can be configured to protect the power MOSFETs under most shortcircuit conditions. The external power MOSFETs are protected from shoot-through by a programmable dead time. I can easily give the input 12v and up to 15 with a bit of fiddling, it is more important for the output to trigger the opto isolators, which will blow at 10 or 12 volts. The half bridge can be controlled by independent logic-level inputs or through the SPI-compatible serial interface. Re: Question regarding an IR2111 half bridge mosfet driver. A bootstrap capacitor is used to provide the above-battery supply voltage required for N-channel MOSFETs. In common with other Allegro A 2SIL™ products, this device incorporates features to complement proper system design, allowing users to achieve the required ASIL level.Ī unique charge pump regulator provides full gate drive for battery voltages down to 5.5 V for most applications. The A4926 is intended for automotive systems that must meet ASIL requirements. The A4926 is an N-channel power MOSFET driver capable of controlling MOSFETs connected in a half-bridge arrangement and is specifically designed for automotive applications with high-power inductive loads, such as brush DC motors solenoids and actuators.
