致新（GMT）原装8A功率级集成G5421CQT1U----G5421科瑞芯电子现货热销中....

       G5421 is a 8A, power stage with integrated 20mΩ N-channel high-side MOSFET and 8.7mΩ N-channel
low-side MOSFET. It includes a tri-state PWM input function. When the PWM input signal stays tri-state,
the tri-state function turns off the high-side MOSFET and low-side MOSFET. The Power-On-Reset (POR)
circuit with hysteresis monitors VCC to start up or shut down the IC. The over-current protection function
monitors the output current without the current sensing resistor that achieves high efficiency and low cost. It
can be enabled by OCEN pin. The skip mode operation is activated by SMOD pin. The G5421 is available
in QFN4X4-23 package.
