Intersil's Compact HIP4086A Three-Phase Bridge Driver IC Features Industry's Fastest Rise and Fall Times

Intersil Corporation (NASDAQ Global Select: ISIL) today introduced the HIP4086A, a low noise, 80V, 0.5A three-phase bridge driver IC. The HIP4086A features low EMI along with the industry's fastest rise and fall times, which help reduce switching losses and simplify development of flexible bridge-based PWM motor control designs. Based on Intersil's proven HIP4086 N-channel MOSFET driver IC, the new HIP4086A integrates three half-bridge gate drivers in one package that can replace larger discrete circuits. It drives 1000pF loads, providing excellent efficiency and high-frequency operation. Rise time is only 50ns (maximum over temperature) compared with competitive devices, which range from 120ns to 200ns. The six N-channel MOSFET drivers can be driven independently so users can configure any switch combination and use the HIP4086A either in brushless DC (BLDC) or switched reluctance motors. The HIP4086A requires no gate drive charge pump, improving EMI performance. Programmable dead time of 0.25 microseconds to 4.5 microseconds avoids cross-conduction or ‘shoot-through' current, also helping reduce EMI and maximizing reliability. Other configurable features include programmable UVLO, bootstrap refresh, an optional charge pump (available in the HIP4086ABZ and HIP4086APZ versions) and a disable input override feature - all programmable using small external components. The HIP4086A is built using a TS16949 automotive quality level process in a TS16949-qualified fabrication facility. It is ideal for battery-powered tools, light electric vehicles and consumer products. Features and Specifications

• 95VDC bootstrap supply simplifies high voltage applications
• Programmable undervoltage lockout (UVLO) guarantees drive integrity
• Disable input pulls all six outputs low to prevent damage to bridge MOSFETs

Pricing and Availability The HIP4086A is available now in a 24-lead SOIC package, and is priced at $2.48 each in 1,000-unit quantities.
