TB62261FTAG TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB62261FTAG PHASE-in controlled Bipolar Stepping Motor Driver The TB62261FTAG is a two-phase bipolar stepping motor driver using a PWM chopper. An interface is PHASE in control. FTAG Fabricated with the BiCD process, rating is 40 V/1.5 A . Features BiCD process integrated monolithic IC. Capable of controlling 1 bipolar stepping motor. P-WQFN36-0606-0.50-002 PWM controlled constant-current drive. Weight: 0.10 g (typ.) Allows full, half, quarter step operation. Low on-resistance (High + Low side = 0.8 (typ.)) MOSFET output stage. High voltage and current (For specification, please refer to absolute maximum ratings and operation ranges) Error detection (TSD/ISD) signal output function Built-in error detection circuits (Thermal shutdown (TSD), over-current shutdown (ISD), and power-on reset (POR)) Built-in VCC regulator for internal circuit use. Chopping frequency of a motor can be customized by external resistor and capacitor. Package TB62261FTAG: P-WQFN36-0606-0.50-002 Note: Please be careful about thermal conditions during use. 2015 TOSHIBA CORPORATION 1 2015-11-6 TB62261FTAG Pin assignment (TB62261FTAG) (Top View) 27 26 25 24 23 22 21 20 19 18 GND NC 28 17 GND 29 OUT B1- VREF B 30 16 OUT B2- VREF A 15 GND 31 TB62261FTAG NC OSCM 14 32 33 13 GND IN A1 IN A2 12 34 OUT A2- 11 OUT A1- PHASE A 35 10 PHASE B 36 GND 1 2 3 4 5 6 7 8 9 Please mount the four corner pins of the QFN package and the exposed pad to the GND area of the PCB. 2 2015-11-6 IN B1 NC IN B2 NC STANDBY VCC GND NC NC VM RS A1 RS B1 RS A2 RS B2 OUT A1 OUT B1 OUT B2 OUT A2
