TMI8118/TMI8118S Application circuit precautions:
1. Do not ground the output pin OUTA/OUTB directly or power supply, because the over-temperature protection mechanism inside the IC is only for high temperature protection, if the peak current is too large, it will burn the IC;
2. Motor blocking transfer because of different motors have different peak currents, if the motor blocking peak current is too large may burn the IC;
3. VDD 电容必需尽可能的靠近芯片 VDD 和 GND 引脚。C1，C2 为 VDD 输入电容，主要作用如下：
3. The VDD capacitor must be as close to the chip VDD and GND pins as possible. C1 and C2 are input capacitors for VDD, and their main functions are as follows:
3.1. absorb the energy released by the motor to the power supply, stabilize the VDD power supply voltage, avoid the IC due to high impulse voltage and direct breakdown, with the function of filtering ripple and interference noise.
3.2. When the motor starts, the current can be released to help the motor start quickly.
3.3. The selection of VDD input capacitor C2 should be based on the voltage stability of VDD and the load current of the motor. If the voltage wave of VDD is larger or the load current of the motor is larger, the larger capacitance value must be selected.
3.4. On the PCB configuration, C1 and C2 capacitors should be as close to VDD as possible. When there is no input signal at the input INA or INB, do not leave the INA or INB pins empty. This prevents a weak leakage current at the P/N junction of the IC body from flowing through the pull-down resistor, which will cause the input potential of the suspended pin to change from low potential to high potential, resulting in incorrect circuit output signals.
