3932 THREE PHASE POWER MOSFET CONTROLLER

RESET. A logic input that enables the device, internally pulled up to LCAP. Logic HIGH will disable the device and turn off MOSFETs, coasting the motor. Logic LOW will enable gate drive to follow commutation logic. This input will override BRAKE. GLC/GLB/GLA. Low side gate drive outputs for external MOSFET drivers. External series gate resistors can be used.

Features

includes gatesource voltage monitor, bootstrap capacitor charging current monitor, undervoltage monitor, motor lead short to supply or ground, and thermal shutdown. 2 RESET 1 PGND 32 AGND 31 DEAD 3 GLC 30 REF 29 SENSE 28 RC 27 PWM 26 TACH 25 SR 24 BRAKE 23 DIR 22 H2 21 H3 20 H1 GHC 5 CC 6 GLB 7 SB 8 4 SC GHB 9 CB 10 GLA 11 SA 12 GHA 13 A3932SEQ ABSOLUTE MAXIMUM RATINGS at TA = +25°C Load Supply Voltage, VBB 50 V VREG (Transient) ...... 15 V Logic Input Voltage Range, VIN ..... -0.3 V to VLCAP + 0.3 V Sense .
