TB62261FTG TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB62261FTG PHASE-in controlled Bipolar Stepping Motor Driver The TB62261FTG is a two-phase bipolar stepping motor driver using a PWM chopper. An interface is PHASE in control. FTG Fabricated with the BiCD process, rating is 40 V/1.8 A . Features BiCD process integrated monolithic IC. Capable of controlling 1 bipolar stepping motor. P-WQFN48-0707-0.50-003 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 TB62261FTG: P-WQFN48-0707-0.50-003 Note: Please be careful about thermal conditions during use. 2015 TOSHIBA CORPORATION 1 2015-11-6 TB62261FTG Pin assignment (TB62261FTG) (Top View) 29 28 26 25 36 35 34 33 32 31 30 27 24 NC 37 NC 23 NC NC 38 22 GND NC 39 21 OUTB 40 GND 20 OUTB VREFB 41 19 GND 42 VREFA FTG 18 GND 43 OSCM 17 OUTA 44 INA1 16 OUTA INA2 45 15 GND 46 PHASEA 14 NC PHASEB 47 13 NC 48 NC 3 6 9 12 1 2 4 5 7 8 10 11 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 NC NC INB1 NC INB2 VCC STANDBY NC GND VM NC NC RSA RSB RSA RSB NC NC OUTA OUTB OUTA OUTB NC NC
