TB62214AFG/AFTG TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB62214AFG, TB62214AFTG BiCD Constant-Current Two-Phase Bipolar Stepping Motor Driver IC The TB62214AFG/AFTG is a two-phase bipolar stepping motor driver using a PWM chopper controlled by clock input. TB62214AFG Fabricated with the BiCD process, the TB62214AFG/AFTG is rated at 40 V/2.0 A . The on-chip voltage regulator allows control of a stepping motor with a single V power supply. M Features Bipolar stepping motor driver PWM constant-current drive Clock input control HSOP28-P-0450-0.80 Allows two-phase, 1-2-phase and W1-2-phase excitations. TB62214AFTG BiCD process: Uses DMOS FETs as output power transistors. High voltage and current: 40 V/2.0 A (absolute maximum ratings) Thermal shutdown (TSD), overcurrent shutdown (ISD), and power-on-resets (PORs) Packages: HSOP28-P-0450-0.80 QFN48-P-0707-0.50 QFN48-P-0707-0.50 Weight HSOP28-P-0450-0.80 : 0.79 g (typ.)
