TB62262FTG TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB62262FTG CLOCK-in controlled Bipolar Stepping Motor Driver The TB62262 is a PWM method clock-in controlled motor driver for two-phase bipolar stepping motor. FTG using a PWM chopper. An interface is CLOCK in control. Fabricated with the BiCD process, rating is 40 V/1.8 A . Features BiCD process integrated monolithic IC. P-WQFN48-0707-0.50-003 Capable of controlling 1 bipolar stepping motor. Weight: 0.10g (typ.) PWM controlled constant-current drive. 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 TB62262FTG: P-WQFN48-0707-0.50-003 Note) Please be careful about thermal conditions during use. 2015 TOSHIBA CORPORATION 1 2015-11-6 TB62262FTG Pin assignment (TB62262) (Top View) 36 35 34 33 32 31 30 29 28 27 26 25 24 NC 37 NC 23 NC NC 38 22 GND NC 39 21 OUTB- 40 GND 20 OUTB- 41 VREFB FTG 19 GND 42 VREFA 18 GND OSCM 43 17 OUTA- 44 CW/CCW 16 OUTA- MO 45 15 GND DMODE1 46 14 NC DMODE2 47 13 NC 48 NC 1 3 4 6 7 9 10 12 2 5 8 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 CLK NC ENABLE VCC RESET NC GND VM NC NC RSA RSB RSA RSB NC NC OUTA+ OUTB+ OUTA+ OUTB+ NC NC
