Automotive brushed DC motor management performs a essential position in trendy autos, enabling environment friendly and dependable operation of techniques corresponding to energy home windows, adjustable seats, sliding doorways, and powered tailgates. These motors present an economical and compact answer for automating important automobile capabilities, enhancing consolation and comfort for customers. Superior motor management techniques additionally guarantee power effectivity, security, and sturdiness by way of options like fault detection and safety mechanisms. Brushed DC motors are extensively utilized in trendy cars for actuators controlling doorways, home windows, seats, and different techniques. Toshiba’s automotive 2-channel half-bridge gate driver IC, the TB9103FTG, gives superior options for environment friendly motor management.Â
This reference design permits engineers to discover two motor management configurations: driving two motors in half-bridge mode or a single motor in H-bridge mode. Key options corresponding to useless time management, built-in fault detection, and fault indication outputs guarantee dependable motor operation with added security and sturdiness. The design additionally helps a broad enter voltage vary, making it adaptable to numerous automotive techniques.
This design simplifies the analysis and testing of the TB9103FTG’s capabilities. It permits motor management by way of guide adjustment by way of onboard switches or exterior management by way of a microcontroller (MCU). The design additionally helps testing with two energy MOSFETs for motor driving: the XPN7R104NC and the XPH3R304PS. Moreover, the design features a reverse connection safety circuit utilizing the XPH1R104PS energy MOSFET, safeguarding the circuit in opposition to incorrect energy provide polarity.
A voltage regulator IC is built-in to generate a secure 5V energy provide, supporting the design and powering an exterior MCU. The TB9005FNG additional enhances system reliability with low-voltage reset, power-on reset, and a watchdog timer, making certain optimum MCU efficiency.
The automotive brushed DC motor management circuit helps half-bridge and H-bridge operation modes, making it versatile for varied functions corresponding to controlling doorways, home windows, and different automotive techniques. Compact in dimension, the board measures 75 mm x 75 mm, making certain simple integration into automotive designs.
The TB9103FTG is a 2-channel half-bridge gate driver designed for automotive functions, which might additionally operate as a 1-channel H-bridge gate driver. It encompasses a low-power sleep mode and incorporates superior fault-detection capabilities. Upon detecting a fault, the machine disables the gate drive and alerts the fault by way of its DIAG terminals.
When paired with an N-channel MOSFET, the TB9103FTG is appropriate for latching motor functions, together with sliding and again doorways, and drive motor functions for seats and home windows generally present in cars. Moreover, it’s well-suited for transitioning motor management techniques from mechanical relays to semiconductor-based options.
