TB62208FG TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB62208FG BiCD Constant-Current Two-Phase Bipolar Stepping Motor Driver IC The TB62208FG is a two-phase bipolar stepping motor driver using a PWM chopper. Fabricated with the BiCD process, the TB62208FG is rated at 40 V/1.8 A. The on-chip voltage regulator allows control of a stepping motor with a single VM power supply. Features HSOP28-P-0450-0.80 - Bipolar stepping motor driver - PWM constant-current drive Weight: 0.79 g (typ.) - Provides phase-A and phase-B enable inputs to allow 2-phase and 1-2-phase excitation. - BiCD process: Uses DMOS FETs as output power transistors. - High voltage and current: 40 V/1.8 A - Thermal shutdown (TSD), over-current shutdown (ISD), and power-on-resets (PORs) for VMR and VCCR - Package: Heat-sink Small Outline Package (HSOP28-P-0450-0.80) © 2014 TOSHIBA Corporation 1 2014-10-01 Block Diagram TB62208FG OSCM Vref_A Vref_B NC NC VCC VM RS_ B NC OUT_ B NC PGND OUT_ B PGND FIN&LOGIC GND 28 27 26 25 24 23 22 21 20 19 18 17 16 15 ～ Reg Pre-driver...
