TB62218AFNG TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB62218AFNG BiCD Constant-Current Two-Phase Bipolar Stepping Motor Driver IC The TB62218AFNG is a two-phase bipolar stepping motor driver using a PWM chopper. Fabricated with the BiCD process, the TB62218AFNG 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 Allows two-phase, 1-2-phase and W1-2 phase excitations. HTSSOP48-P-300-0.50 BiCD process: Uses DMOS FETs as output power transistors. High voltage and current: 40 V/2.0 A (absolute maximum Weight: 0.21 g (typ.) ratings) Thermal shutdown (TSD), overcurrent shutdown (ISD), and power-on resets (PORS) Packages: HTSSOP48-P-300-0.50 2014 TOSHIBA Corporation 1 2014-10-01 TB62218AFNG Pin Assignment TB62218AFNG (Top View) OSCM 1 48 VREF A NC 47 VREF B 2 IN A1 46 GND 3 IN A2 4 45 NC PHASE A 5 44 NC NC 6 43 NC 42 PHASE B 7 NC IN B1 8 41 VCC IN B2 9 40 NC 10 39 V STANDBY M GND 11 38 NC NC 12 37 NC RS A1 13 36 RS B1 TB62218AFNG RS B2 RS A2 14 35 NC 15 34 NC OUT A1 16 33 OUT B1 OUT A2 17 32 OUT B2 NC 18 31 NC NC 19 30 NC GND 20 29 GND NC 21 NC 28 22 OUT A1 OUT B1 27 23 OUT A2 26 OUT B2 GND 24 25 GND 2 2014-10-01
