The L6219R013TR is a PMIC (Power Management IC), specifically a motor driver, controller from STMicroelectronics. It is designed for the control of brushless DC (BLDC) motors, as well as fans and other industrial applications.

The device uses a 3 phase inverter with six N-channel MOSFETs, which are driven by three independent half bridges and complemented by two diodes each. This implies that it requires seven external components in order to provide a complete 3-phase power stage.

The L6219R013TR also includes all the logic circuits necessary to implement a sensorless sinusoidal motor control. Consequently, it is ideal for the operation of a wide range of motors, such as DC brushless, stepper, three-phase sinusoidal motors and so forth. An integrated bootstrap circuit enables the use of very small gate drivers and requires no external components.

The current sense feature of this device is a combination of an internal current sense amplifier and an external current sense resistor. This combination provides an accurate current-limiting loop, allowing the current to be set from a very small value to the maximum current limit specified by the device.

The device is also capable of controlling the speed of the motor, either directly through the PWM signal, or by using an external speed regulator (taking the input from a tachometer). The device also includes advanced protections against overcurrent and overtemperature. Moreover, the built-in temperature sensing feature provides an additional temperature protection.

Furthermore, the device includes an on-chip diagnostic with a failure mode diagnosis function that allows the user to investigate and identify fault conditions. It also offers an enable input and a driver error flag output. The enable input allows the user to enable/disable the device, whereas the driver error flag provides the information regarding a system or component fault condition.

In conclusion, the L6219R013TR provides an accurate and cost-effective solution for the control and protection of BLDC motors, as well as other industrial applications. It is a very powerful motor driver and controller with a variety of features and high reliability.
