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.

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.

NOTE: Intersil Pb-free products employ special Pb-free material

sets; molding compounds/die attach materials and 100% matte tin

plate termination finish, which is compatible with both SnPb and

Pb-free soldering operations. Intersil Pb-free products are MSL

classified at Pb-free peak reflow temperatures that meet or exceed

the Pb-free requirements of IPC/JEDEC J Std-020B.
