TPS2202AIDB

Power management integrated circuits (PMIC) are ubiquitous in today’s electronics and have become an essential part of the design process. They enable power savings, reduce power losses, and enable efficient distribution and utilization of the available power. In some systems, such as industrial and automotive applications, specific PMIC devices are required to ensure safety and proper performance. The TPS2202AIDB is a PMIC designed specifically for industrial and automotive environments, providing power distribution switches, load drivers, and a variety of other functions.

Application Field

The TPS2202AIDB is designed for industrial and automotive applications. It has the capability to switch and control multiple power sources, such as Li-ion batteries and AC line power sources. The device is capable of managing voltages ranging from 6V to 18V and up to 8A of current. It also includes a range of protection features, such as over-voltage protection (OVP) and over-temperature protection (OTP), to ensure system-level performance and safety.

The device can be used in a wide range of applications, such as battery management systems, motor control, LED lighting, and power supplies. The device is particularly well-suited for industrial and automotive environments, where safety and reliability are paramount.

Working Principle

The TPS2202AIDB is a multi-channel PMIC that combines a variety of power distribution switches and load drivers. The device contains two power switches, two load drivers, and one open drain output. It also offers a range of protection features, such as over-voltage protection (OVP) and over-temperature protection (OTP).

The device uses a combination of low side N-channel MOSFETs and high side MOSFETs. The high side MOSFETs are configured as source followers, allowing them to control higher voltage sources. The low side MOSFETs are configured as cascodes, which allows them to source or sink higher current.

The two load drivers are controlled by two enable pins, which are used to enable or disable the two loads. The open drain output is used to communicate with other ICs in the system, such as microcontrollers. Finally, the device also provides enable and status pins, which can be used to check the status of the device.
