PMIC stands for Power Management Integrated Circuit, and gate drivers are devices which provide the necessary phase current for driving the gate of high voltage power devices. Gate drivers also provide functionalities such as protection and protection control, gate observations and measurements, breakdown detection and prevention.

The TSC428MJA/883B is a single-channel driver designed to drive the gate of MOSFETs, IGBTs and other power devices through its output stage AOUT (Analog Output). Its integrated features like linear current sensing, adjustable SLOPE, pull low/high capability maximise efficiency, reduce propagation delays, minimise switching losses and EMI emissions to achieve the best power efficiency and speed.

The main application field for the TSC428MJA/883B as a PMIC - Gate Driver is for low-side drivers for automotive applications.

The TSC428MJA/883B has two main components: the pulse-width modulated (PWM) controller and the outputs stage. It also features a wide voltage range of 6V to 24V, and a low quiescent current of 20μA.

The PWM controller determines the duty cycle and operating frequency of the power MOSFET by varying its PWM signal. The PWM signal is sent through a comparator to the outputs stage, which translates it into a low-voltage high-current AOUT signal. This signal is then used to drive the gate of the power MOSFETs, providing the necessary phase current.

The TSC428MJA/883B also has protection and protection control features. The outputs stage can be configured to improve protection from short-circuits, over-voltage, over-current, and over-temperature. Additionally, the TSC428MJA/883B has various gate observation and measurement capability that includes a gate-charge feedback pin (GTE) which helps to monitor the gate-current and indicates when the gate is on and off. This signal can be used to detect a breakdown before it happens, allowing time for corrective action to be taken.

The TSC428MJA/883B is exceptionally suited for automotive applications and can be used in a variety of applications that require power control and gate driving. It is a robust and reliable device, providing protection features, gate observations, and measurements that maximise efficiency, reduce propagation delays, and minimise switching losses and EMI emissions.
