www.DataSheet4U.com Freescale Semiconductor, Inc. Document order number: MC33395/D Rev 2.0, 01/2004 MOTOROLA SEMICONDUCTOR TECHNICAL DATA Advance Information Three-Phase Gate Driver IC The 33395 simplifies the design of high-power BLDC motor control design by combining the gate drive, charge pump, current sense, and protection circuitry necessary to drive a three-phase bridge configuration of six N-channel power MOSFETs. Mode logic is incorporated to route a pulse width modulation (PWM) signal to either the low-side MOSFETs or high-side MOSFETs of the bridge, or to provide complementary PWM outputs to both the low- and high-sides of the bridge. 33395 33395T THREE-PHASE GATE DRIVER IC Freescale Semiconductor, Inc... Detection and drive circuitry are also incorporated to control a reverse battery protection high-side MOSFET switch. PWM frequencies up to 28 kHz are possible. Built-in protection circuitry prevents damage to the MOSFET bridge as well as the drive IC and includes overvoltage shutdown, overtemperature shutdown, overcurrent shutdown, and undervoltage shutdown. The device is parametrically specified over an ambient temperature range of -40°C ≤ TA ≤ 125°C and 5.5 V ≤ VIGN ≤ 24 V supply.
