Blog Article

JSM6288Q is a high-voltage, high-speed power MOSFET high- and low-side driver chip. It uses high- and low-voltage compatible processes to enable high- and low-side gate drive circuits to be integrated on a single chip. It has independent high-side and low-side reference output channels. The JSM6288Q logic input level is compatible with CMOS or LSTTL logic output levels as low as 3.3V, and the output has large current pulse capability and dead zone logic to prevent direct pass.
