DATASHEET HIP4086, HIP4086A FN4220 Rev 1.00 80V, 500mA, 3-Phase MOSFET Driver January 12, 2017 The HIP4086 and HIP4086A (referred to as the HIP4086/A) Features are 3-phase N-channel MOSFET drivers. Both parts are Independently drives 6 N-channel MOSFETs in 3-phase specifically targeted for PWM motor control. These drivers bridge configuration have flexible input protocol for driving every possible switch combination. The user can even override the shoot-through Bootstrap supply maximum voltage up to 95VDC with bias protection for switched reluctance applications. supply from 7V to 15V The HIP4086/A have a wide range of programmable dead 1.25A peak turn-off current times (0.5s to 4.5s) which makes them very suitable for the User programmable dead time (0.5s to 4.5s) low frequencies (up to 100kHz) typically used for motor drives. Bootstrap and optional charge pump maintain the high-side The only difference between the HIP4086 and the HIP4086A driver bias voltage. is that the HIP4086A has the built-in charge pumps disabled. Programmable bootstrap refresh time This is useful in applications that require very quiet EMI Drives 1000pF load with typical rise time of 20ns and fall performance (the charge pumps operate at 10MHz). The time of 10ns advantage of the HIP4086 is that the built-in charge pumps allow indefinitely long on times for the high-side drivers. Programmable undervoltage set point To insure that the high-side driver boot capacitors are fully Applications charged prior to turning on, a programmable bootstrap refresh pulse is activated when VDD is first applied. When active, the Brushless Motors (BLDC) refresh pulse turns on all three of the low-side bridge FETs 3-phase AC motors while holding off the three high-side bridge FETs to charge the Switched reluctance motor drives high-side boot capacitors. After the refresh pulse clears, normal operation begins. Battery powered vehicles Another useful feature of the HIP4086/A is the programmable Battery powered tools undervoltage set point. The set point range varies from 6.6V to 8.5V. Related Literature AN9642, HIP4086 3-Phase Bridge Driver Configurations TABLE 1.
