80V/0.3A Peak Three Phase High Side Driver


The HIP4083 is a three phase high side N-channel MOSFET driver, specifically targeted for PWM motor control. Two HIP4083 may be used together for 3 phase full bridge applications (see application block diagram). Alternatively, the lower gates may be controlled directly from a buffered microprocessor output.

Unlike other members of the HIP408x family, the HIP4083 has no built in turn-on delay. Each output (AHO, BHO, and CHO) will turn-on 65ns after its input is switched low. Likewise, each output will turn-off 60ns after its input is switched high. Very short and very long dead times are possible when two HIP4083 are used to drive a full bridge. This dead time is controlled by the input signal timing.

The HIP4083 does not have a built in charge pump. Therefore, the bootstrap capacitors must be recharged on a periodic basis by initiating a short refresh pulse. In most bridge applications, this will happen automatically every time the lower FETs turn-on and the upper FETs turn-off. However, it is still possible to use the HIP4083 in applications that require the high side FETs to be on for extended periods of time. This can be easily accomplished by sending a short refresh pulse to the DIS pin.

The HIP4083 has reduced drive current compared to the HIP4086 making it ideal for low to moderate power applications. The HIP4083 is optimized for applications where size and cost are important. For high power applications driving large power FETs, the HIP4086 is recommended.
