The characteristics and advantages of TMC7300-LA-T include a voltage range of 2V (1.8V) Operating 1-2 lithium-ion batteries with 11V DC batteries, or at least 2 AA/NiMh batteries with 1/2 DC motors, up to 2A/2.4A, with direct bridge control for speed and torque control solenoids, relays, lights, motors Single wire UART, used for dual motor torque and speed control standby<50nA, typical current consumption low conduction current LS 170m Ω and HS 170m Ω (typical value), parallel single DC motor option provides comprehensive motor load feedback protection and diagnosis, micro QFN 3 * 3, with 20 pins
The TMC7300-LA-T operates on single or dual lithium-ion batteries or dual or multiple AA batteries, making it ideal for battery powered devices. Its two full bridges allow for the control of two DC motors, PWM control of LEDs, or the use of a polarity signal per half bridge for protected independent peripheral drive. Through simple UART control, up to two DC motors can be operated to achieve direction, speed, and torque. Integrated power MOSFET and internal charge pump, capable of achieving first-class RDSon even at low power supply voltage, continuously processing motor currents of up to 1.2A per motor, or dual currents in parallel. In addition, the small standby current ensures a longer battery life. The protection and diagnostic functions support robust and reliable operation.
