TB67H400AFNG TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB67H400AFNG PWM Chopper-Type Brushed DC Motor driver The TB67H400AFNG is brushed DC motor driver of a PWM chopper-type. The TB67H400AFNG 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 TB67H400AFNG is rated at 50 V, 4.0 A (2ch)/8.0 A HTSSOP48-P-300-0.50 (1ch). Weight: 0.21 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 TB67H400AFNG Pin assignment OSCM 1 48 HBMODE NC 47 VREF 2 INA1 46 GND 3 4 NC INA2 45 PWMA 5 44 NC 6 NC NC 43 PWMB 42 NC 7 INB1 8 41 VCC INB2 9 40 NC VM TBLKAB 10 39 TB67H400AFNG GND 11 38 NC (Top View) NC 12 37 NC RSA 13 36 RSB RSB RSA 14 35 NC 15 34 NC OUTA+ 16 33 OUTB+ OUTA+ 17 32 OUTB+ NC 18 31 NC NC 19 30 NC GND GND 20 29 21 NC NC 28 OUTA- 22 OUTB- 27 23 OUTA- 26 OUTB- GND 24 25 GND Note: Please connect the HTSSOP exposed pad to the PCB ground pattern. 2016-12-22 2
