The HIP4084 is a Four Phase Bridge N-Channel MOSFET
driver IC.
Specifically targeted for PWM and stepper motor control
applications, the HIP4084 makes bridge based designs sim-
ple and flexible. With operation up to 80V and undervoltage
detection, the device is best suited to applications of moder-
ate power levels.
Like the HIP4081, the HIP4084 has a flexible input protocol
for driving every possible switch combination. Like the
HIP4082, the HIP4084 provides a typical drive currents of
0.5A and a programmable dead time from 0.25µs to 4.5µs.
Like the HIP4086, the HIP4084 allows override of shoot-
through protection for switched reluctance applications. The
HIP4084 is suitable for applications requiring DC to 100kHz.
Unlike other HIP4080 family products, the HIP4084 pro-
vides, from a single pin, a programmable undervoltage set
point and an enable/disable function.
