HIP4083EVAL

The HIP4083EVAL is an evaluation board for evaluating HIP4083 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. 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.

• Independently drives three high side N channel MOSFETs in three phase bridge configuration
• Bootstrap supply max voltage to 95Vdc
• Bias supply operation from 7V to 15V
• Drives 1000pF load with typical rise times of 35ns and fall times of 30ns
• CMOS/TTL compatible inputs
• Programmable under voltage protection
