A3932
A3932 is Three-Phase Power MOSFET Controller manufactured by Allegro MicroSystems.
feature will short out the current path through the power MOSFETs intrinsic body diodes during PWM off cycle current decay. This can minimize power dissipation in the MOSFETs, eliminate the need for external power clamp diodes, and potentially allow a more economical choice for the MOSFET drivers. The A3932 provides mutation logic for Hall sensors configured for 120-degree spacing. The Hall input pins are pulled up to an internally generated 5V reference. Power MOSFET protection 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 Voltage, VSENSE -5 to 1.5 V Pins SA/SB/SC, -5 to 50 V Pins GHA/GHB/GHC -5 to VBB + 17 V Pins CA/CB/CC SA/SB/SC+17 V Package Power Dissipation (TA = +25°C) RØJA 52.4 °C/W RØJC 22.7 °C/W PD 2.4 W Operating Temperature Range, TA -20°C to +85°C Junction Temperature, TJ +150°C Storage Temperature Range, TS -55°C to +150°C 14 CA 15 VREG 16 LCAP 17 FAULT 18 MODE 19 VBB FEATURES n Drives Wide Range of N-channel MOSFETs n Sources 1.25A for Gate Turn-On n Sinks 2.5A for Gate Turn-Off n Synchronous Rectification n Power MOSFET Protection n Adjustable Dead Time...
