TB62208FNG TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB62208FNG BiCD Constant-Current Two-Phase Bipolar Stepping Motor Driver IC The TB62208FNG is a two-phase bipolar stepping motor driver using a PWM chopper. Fabricated with the BiCD process, the TB62208FNG 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. HTSSOP48-P-300-0.50 Features Bipolar stepping motor driver Weight: 0.21g (typ.) PWM constant-current drive Provides phase 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: HTSSOP48-P-300-0.50 (with thermal pad at bottom) 1 2011-01-28 TB62208FNG Block Diagram 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 Reg Pre-driver ISD Comparator TSD Comparator ISD Control Pre-driver 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 In the block diagram, part of the functional blocks or constants may be omitted or simplified for explanatory purposes. 2 2011-01-28 OSCM Vref A NC Vref B NC LGND NC NC PHASE A NC NC NC NC PHASE B ENABLE A VCC ENABLE B NC VM STANDBY NC LGND NC NC RS A1 RS B1 RS A2 RS B2 NC NC OUT B1 OUT A1 OUT A2 OUT B2 NC NC NC NC PGND PGND NC NC OUT B1 OUT A1 OUT A2 OUT B2 PGND PGND
