TB67S215FTAG,EL  is a driver IC for high-current, high-voltage, two-phase stepper motors and small motors. This chip is designed for precision small size applications, using a low voltage power supply and low power consumption. The device has advanced features including a 10 μA current sense amplifier and a 0.1 Ω current sense resistor.The TB67S215FTAG,EL belongs to a class of motor driver ICs, called "PMIC - Motor Drivers, Controllers". PMIC (Power Management Integrated Circuit) is an all-in-one chip which integrates several power management, motor control, and safety functions into a single device. PMICs are typically used in motor driver applications including motor speed control, motor direction control, motor power on/off control and motor position sensing.The TB67S215FTAG,EL motor driver IC is designed for DC Brushless Motor (BLDC) and Small Motors. The IC provides high current drive capability and maximum output voltage of 28V. It is designed to operate over a wide temperature range of -40 to 85℃. The device has integrated dual H-bridge circuit, adequate current drive capability, and PWM frequency up to 250kHz. It also has a built-in protection circuit that blocks energy surge from the motor.The working principle of the TB67S215FTAG,EL is based on the dual H-Bridge circuit. An H-Bridge circuit is a combination of switches which can allow the electric current to flow through a bi-directional path. The TB67S215FTAG,EL provides two H-Bridge circuits, one for each of the phase winding. When power is applied to the phase winding of the motor, the H-Bridge switches will open, allowing the current to flow through the motor winding and generate a torque.The TB67S215FTAG,EL motor driver IC features a PWM (Pulse Width Modulation) output which operates in cycles of slightly varying width, thereby changing the output voltage. This provides precision control over the motor speed. The IC also has two 3-level inputs for low speed ramp (start/stop) control and two 5-level inputs for digital control.The TB67S215FTAG,EL has several safety features such as current limit and thermal shutdown. The current limit prevents the motor from drawing high current in case of motor fault or other system failures. The thermal shutdown function is used to protect the IC from overheating. The device has an on-chip oscillator and automatic disable in case of short circuit.In summary, the TB67S215FTAG,EL is a high-current, high-voltage, two-phase stepper motor driver IC that combines a dual-H-bridge and low voltage power supply with low power consumption. The device has advanced features including a 10 μA current sense amplifier and a 0.1 Ω current sense resistor. It also has integrated safety features such as current limit and thermal shutdown that protect the IC from system faults and power surges. The TB67S215FTAG,EL is ideal for precision small size applications and provides reliable control of DC Brushless Motor and small motors.
