TB62218AFG/AFTG TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB62218AFG, TB62218AFTG BiCD Constant-Current Two-Phase Bipolar Stepping Motor Driver IC The TB62218AFG/AFTG is a two-phase bipolar stepping motor TB62218AFG driver using a PWM chopper. Fabricated with the BiCD process, the TB62218AFG/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 HSOP28-P-450-0.80 PWM constant-current drive TB62218AFTG Allows two-phase, 1-2-phase and W1-2 phase excitations. 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-0450-0.8 QFN48-P-0707-0.50 QFN48-P-0707-0.50 Weight HSOP28-P-0450-0.80: 0.79 g (typ.)
