TB67H400AFTG TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB67H400AFTG PWM Chopper-Type Brushed DC Motor driver The TB67H400AFTG is brushed DC motor driver of a PWM chopper-type. The TB67H400AFTG is a dual channel H-SW driver which can control two brushed DC motors. Moreover, the parallel control function (Large mode) of an output part is built in, and 1ch high current drive is also possible. Fabricated with the BiCD process, the TB67H400AFTG is rated at 50 V, 4.0 A (2ch)/8.0 A P-WQFN48-0707-0.50-003 (1ch). Weight: 0.10 g (typ.) Features Monolithic motor driver using BiCD process. Capable of controlling two brushed DC motor. 2 drive modes (PWM controlled constant current/ direct PWM) 4 operation modes (Clock-wise/Counter clock-wise/Brake/Stop (Off)) Low on-resistance output stage (High side+Low side:0.49 (typ.)) High voltage and current (for specification, please refer to absolute maximum ratings and operating ranges.) Built-in error detection circuits (Thermal shutdown (TSD), over-current detection (ISD), and power-on reset (POR)). The VCC regulator for internal circuit operation is built in. Able to customize PWM (internal chopping) frequency by external components. Note: Please be careful about the thermal conditions during use. 2016-12-22 2016 TOSHIBA CORPORATION 1 TB67H400AFTG Pin assignment 34 33 32 31 30 29 28 27 36 35 26 25 24 NC 37 NC 23 NC NC 38 22 GND NC 39 21 OUTB- 40 GND 20 OUTB- 41 VREF TB67H400AFTG 19 GND HBMODE 42 (Top View) 18 GND OSCM 43 17 OUTA- 44 INA1 16 OUTA- INA2 45 15 GND 46 PWMA 14 NC 47 PWMB 13 NC 48 NC 1 3 4 6 7 9 10 12 2 5 8 11 Note: Please connect the WQFN package corner pad and the exposed pad to the PCB ground pattern. 2016-12-22 2 NC NC INB1 NC INB2 VCC TBLKAB NC GND VM NC NC RSA RSB RSA RSB NC NC OUTA+ OUTB+ OUTA+ OUTB+ NC NC
