HA13605A

HA13605A Three-Phase Brushless Motor Driver ADE-207-201A (Z) 2nd. Edition February, 1998 Description The HA13605A is a three-phase brushless motor driver IC that provides digital speed control on chip. It was developed for use as the drum motor driver in plain paper copiers and has the following functions and features. Functions Three-phase output circuit that can provide a maximum of 4.5 A at 35 V per phase Digital speed control Crystal oscillator circuit (10 MHz maximum) FG amplifier Speed monitor (lock detection output) Current control circuit Overvoltage protection circuit (OVSD) Thermal protection circuit (OTSD) Low voltage protection circuit (LVI) Forward/reverse switching circuit Features High breakdown voltage, large currents Direct PWM drive outputs Employs DMOS Low on resistance: 0.7 Ω/DMOS maximum No lower arm flywheel diode is required HA13605A Pin Description Pin No. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 Pin Name VCC UOUT BOOSTL VOUT RNF WOUT BOOSTH UIN VR1 VIN VX1 WIN C-PMP FGINFGOUT FGIN+ DIR PWMOSC DSEL OSCOUT READY OSCIN GND Function Power supply U phase output Booster pin.
