HIP4083
80V, 300mA 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.
