The BTS6163DNT is a monolithic high-side power switch integrated circuit (IC) from STMicroelectronics. This particular IC is part of the STMicroelectronics Power Management, Protection, and Control (PMIC) portfolio of products. PMICs are integrated circuits that enable the design of power management systems with centralized, autonomous, and optimized control.

The BTS6163DNT IC is designed to help control the power distribution of high power loads with a variety of circuit protection features. It is a current limiting device that works as an intermediate between the battery and electronic load. This high-side switch can be used in a variety of applications, from automotive to industrial and more. The device is suitable for high-power and high-current applications, such as those found in starter systems, solenoid control, and other automotive electronics.

This power management IC features a high integration level, offering an improved cost/performance ratio as well as ease of use. It has an on-chip 55 mOhm power MOSFET with a built-in current and temperature sensor, thermal protection, short-circuit protection, and other features to ensure reliable operation at high power and current levels. The device also features a patented embedded high-side current loop technology (HSCI) that automatically reduces the current and protects the system in the event of an over-current situation.

The BTS6163DNT is a load driver IC that works by driving a power MOSFET with a high side, low side, or high side/low side control approach. It is designed for use with 5V logic inputs, allowing for flexible control. The device also includes protection against output leakage from the load. In addition, the IC includes protection from fast over-current conditions and thermal overloads.

In terms of application fields, the BTS6163DNT can be used for powering linear and DC motors, as well as a variety of other applications. The device is suitable for use in automotive, industrial, and consumer applications, thanks to its low power consumption, high integration level, and wide operating temperature range. The device also features short-circuit protection, thermal protection, and over-current protection features, making it a reliable and robust power solution.

The working principle of the BTS6163DNT is simple. When power is applied to the load, the power MOSFET is turned on. This is done by a controlled gate voltage that can be controlled according to the signal provided to the IC’s logic inputs. Once the load is connected, current flows between the load and the MOSFET to activate the power switch and power the load. During the on-state phase, the power MOSFET is switched off using a hardware-based current protection loop.

In addition to providing power to the load, the BTS6163DNT also offers protection features for over-current, short-circuit, and thermal conditions. It features a built-in current protection loop that monitors the load current and shuts down the power switch in case of an overload. The device also features a thermal overload protection circuit that reduces the current in case of an over-temperature condition to protect the device and load from damage.

In conclusion, the BTS6163DNT from STMicroelectronics is a high-side power switch IC that is part of the PMIC portfolio of products. This device is suitable for high-powered and high-current applications, such as starter systems, solenoid control, and other automotive electronics. It features a high integration level, offering an improved cost/performance ratio as well as ease of use. The device also includes protection from output leakage from the load, fast over-current conditions, and thermal overloads. The device is suitable for use in automotive, industrial, and consumer applications.
