The TMI8723 is a gate driver IC designed for H- bridge driver applications. It is capable of driving H-bridge consisting of four N- channel power MOSFETs up to 40V. The TMI8723 integrates a regulated charge pump to generate gate drive power,Peak Sink and Source current can be 500mA and 250mA. At the same time, TMI8723 can set the value of the overcurrent point through the pin VDS. Internal protection features include programmable short-circuit protection, over- current protection, undervoltage lockout, and thermal shutdown. The TMI8723 is available in a QFN-16 (3mmx3mm) package with an exposed thermal pad.
