The APW 8707B integrates a high-side N-channel

MOSFET and a low-side N-channel MOSFET with adap-

tive dead-time control. The APW8707B have a built-in tri-

state PWM input function which can support a number of

PWM controllers. When the PWM input signal stays tri-

state, the tri-state function shuts off the high-side MOSFET

and turns on the low-side MOSFET without consider ZC

function. The device is also equipped with Power-On-

Reset(POR) and enable control functions into a single

package and accurate current limit. The device over-cur-

rent protection monitors the output current by using the

voltage drop across the R

nating the need for a current sensing resistor that fea-

tures high efficiency and low cost. The POR circuit with

hysteresis monitors VCC supply voltage to start up/shut-

down the IC at power-on/off. The APW8707B also can be

enabled or disabled by other power system. Pulling the

EN pin high or low will turn on or shut off the device.
