The STMPS2272TTR is part of a new generation of power management integrated circuits (PMIC) specifically designed for load power distribution and load driving applications. In the present market, there are diverse load power distribution and load driving products, but the STMPS2272TTR stands out for its simple, low-cost, low-power architecture and its high on-state efficiency over a wide range of operating temperatures.

The STMPS2272TTR is a high-speed, low-voltage power distribution switch that is designed to control power to multiple loads from a single source in a distributed system. It operates with a supply voltage supplied externally via a dedicated voltage regulator or through a regulated voltage line from a local power supply. It also draws power from the same regulated voltage line, eliminating the need for a dedicated supply voltage. The STMPS2272TTR is capable of driving up to 25A of current, making it suitable for powering high-power loads such as motors, pumps and fans.

The STMPS2272TTR is constructed using a two-level gate driver circuit, featuring an active high driver on the output side and a low impedance, low-side gate driver on the input side. This circuitry allows the STMPS2272TTR to support up to 25A of current with a minimum on-state voltage drop of 0.2V and a maximum on-state efficiency of 99%. The device is also designed to support power distribution in a wide range of environment temperatures (from –40°C to +125°C).

The STMPS2272TTR provides a highly efficient solution for controlling the power distribution in a variety of applications, including motor and fan control, power sequencing, power management, load switching, and load balancing. The two-level gate driver architecture allows the STMPS2272TTR to support fast on-off switching and soft-start operations. Additionally, the device has a slew rate of 1V/us, making the STMPS2272TTR suitable for applications that require fast transient response times.

The STMPS2272TTR is designed to provide enhanced system protection with over-voltage and over-current protection as well as short-circuit and over-temperature protection. The device also has a built-in ‘Power Down’ (LD) pin which allows for safe, quick shutoff of the device. In addition, the device’s driver circuitry allows the device to maintain a low output impedance even under high-di/dt conditions.

The STMPS2272TTR is a great choice for power distribution applications that require high efficiency and system protection features. Its low-voltage, two-level gate driver architecture make it ideal for load power distribution and load power driving applications as well as motor and fan control, power sequencing, and load balancing applications. It is also capable of driving up to 25A of current while operating over a wide range of temperature conditions. Its features such as over-voltage, over-current, and over-temperature protection make it a safe and reliable choice for a variety of power distribution applications.
