A6841SLW-T is a power management integrated circuit (PMIC) which belongs to the family of Power Distribution Switches, Load Drivers. It provides an automotive Gate driver solution with advanced features and can support a wide range of applications. A6841SLW-T is an integrated PMIC and is typically used in automotive applications with high current loads. This product includes two independent high and low side drivers, two independent protection circuits, and two low and low side current sensors.

A6841SLW-T provides many benefits to automotive applications, such as high current capability, thermal margin, system level and functional diagnostics, as well as over-voltage and over-temperature protection. It also offers a low quiescent current and low shutdown current, allowing the PMIC to be used in low power applications. System level diagnostics and protection features provide enhanced system robustness.

The A6841SLW-T working principle is simple yet powerful. The PMIC uses a high- and low-side N-Channel MOSFETs with a control input from an external motor control unit. The operation of the high-side switch is controlled by the HIGH side EN input, and the operation of the low-side switch is controlled by the LOW side EN input. The output of the drivers is routed through two independent current sensors that measure the current going through the top- and bottom-side switches. The current feedback is overseen by the microprocessor embedded in the IC, that monitors and exhibits collected information to the user.

The A6841SLW-T PMIC is used in various automotive applications including driving LED light strips, driving brushless DC motors, powering automotive infotainment systems, and driving high-side loads. The product optimizes system efficiency and reduces system power losses. The high-side and low-side switches are designed with a maximum continuous current of 2A, with a maximum Switching frequency of 400kHz. The PMIC enables adjustable soft start, to be adjusted for a low Voltage overshoot and reduce Inrush currents. It also provides reverse current protection, as well as Short circuit protection.
