Page 2: Product Outline
Product Outline The TB67H400AHG is a dual channel DC brushed Motor Driver that supports both the constant current PWM control and the direct PWM control, and is capable to control two DC brushed DC independently. By adopting Bi-CD process, maximum Output withstand voltage of 50V and maximum Output current of 4.0A/channel as absolute maximum ratings are realized. - Page 3 Basic Notes in use of this evaluation board Power Supply Voltage and Operating Range In using the TB67H400AHG, the voltage should be applied to the VM and VREF pins. The absolute maximum rating of VM (Power supply voltage for motor) is 50V, but operating range of the power supply is 10 to 47V.
- Page 4 Explanation of Each Abnormality Detection Circuit TSD (Thermal Shut Down) When the junction temperature (Tj) of this chip exceeds 160°C(typ.),a internal detection circuit stars operation and all outputs are turned off. In the operating state of TSD, IC stays stop mode. After TSD operation, this is canceled by turning the power supply on again or setting to standby mode once by (IN1A, IN2A, IN1B, IN2B, PWMA, PWMB=all Low) and then releasing it.

- Page 7 Setting Evaluation Board :1 Setting Motor Current The TB67H400AHG conducts motor operation by PWM constant current control which is based on the frequency of the OSCM oscillation circuit. The maximum current value (set Motor current value) can be determined by a sense resistor (RRS) and the reference voltage (Vref).
- Page 8 Setting Evaluation Board :2 Setting the Chopping Frequency for constant current PWM control In PWM control of the TB67H400AHG, the internal oscillation frequency (fOSCM) and the chopping frequency (fchop) can be adjusted according to the constant of the external components those are connected to the OSCM pin.
- Page 9 VDD pin On this evaluation board, jumpers as shown in the picture above are provided for setting operation of TB67H400AHG When selecting functions by using jumpers, please short the JP_VCC, or supply high level from the VDD pin. The characters surrounded by white square frame close to the jumpers show the Level (H/L).
