TB62214AFNG TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB62214AFNG BiCD Constant-Current Two-Phase Bipolar Stepping Motor Driver IC The TB62214AFNG is a two-phase bipolar stepping motor driver using a PWM chopper controlled by clock input. Fabricated with the BiCD process, the TB62214AFNG 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 HTSSOP48-P-300-0.50 Allows two-phase, 1-2-phase and W1-2-phase excitations. BiCD process: Uses DMOS FETs as output power transistors. Weight : 0.21 g (typ.) High voltage and current: 40 V/2.0 A (absolute maximum ratings Thermal shutdown (TSD), overcurrent shutdown (ISD), and power-on-resets (PORs) Packages: HTSSOP48-P-300-0.50 1 2012-04-17 TB62214AFNG Pin Assignment TB62214AFNG (Top View) OSCM 1 48 VREF A NC 47 2 VREF B 46 CW/CCW 3 GND 4 45 NC MO OUT D MODE1 NC 5 44 NC NC 6 43 NC D MODE2 7 42 CLK 8 41 VCC ENABLE 9 40 NC V 10 39 M RESET GND 11 NC 38 NC NC 12 37 RS A1 13 36 RS B1 TB62214AFNG RS A2 14 35 RS B2 NC 15 34 NC OUT A1 16 33 OUT B1 OUT A2 17 32 OUT B2 NC 18 31 NC NC NC 19 30 GND 20 GND 29 21 NC NC 28 OUT A1 22 27 OUT B1 23 OUT A2 26 OUT B2 GND 24 25 GND 2 2012-04-17
