Shenzhen Mingjiada Electronics Co., Ltd. a globally renowned independent distributor of electronic components, has long specialized in the supply and recycling of motor drive and power management chips. The company now prioritizes supplying brand-new, genuine units and offering premium cash purchases for the TMI8180A brushed DC (BDC) motor driver from Toll Microelectronics. Featuring high integration, built-in current detection, and comprehensive protection functions, this product has become an ideal choice for smart home, office equipment, industrial control, and medical electronics applications.
TMI8180A Product Overview
The TMI8180A is a versatile motor driver suitable for multiple applications. This device integrates an N-channel H-bridge, charge pump regulator, current detection and regulation, current proportional output, and protection circuits. The charge pump enhances system efficiency by supporting high-side N-channel MOSFETs and 100% duty cycle operation.
Integrated current sensing enables the driver to regulate motor current during startup and high-load conditions. Current limiting is configurable via an adjustable external voltage reference. Additionally, the device provides an output current proportional to the motor load current, facilitating detection of motor stall or load condition changes.
A low-power sleep mode enables ultra-low quiescent current consumption. When using the TMI8180A, ensure the nSLP pin transitions high for at least 3 milliseconds after power-up. The device incorporates comprehensive fault protection, including under-voltage lockout (UVLO), output overcurrent protection (OCP), and thermal shutdown (TSD).
