STMPS2262TTR Application Field and Working PrinciplePower Distribution Switches, Load Drivers (PDs) provide intelligent, automated control of power supplies, loads, or power switches to accurately regulate current, voltage, and power flow. STMPS2262TTR is a small and low-cost PD controller that features robust current and voltage monitoring, over-temperature protection, over-current protection and a wide range of application flexibility.Application Field of STMPS2262TTRSTMPS2262TTR is designed for a wide range of applications, providing efficient and reliable power management for AC/DC systems. It is most commonly used in computers, consumer electronics, networking systems, industrial automation, and automotive applications. The device can be used for current-regulated applications such as switched-mode power supplies, motor drives, and lighting control, as well as voltage regulated processes such as continuous synchronous rectification, high/low voltage selectors, and load switches.Principle of Working of STMPS2262TTRThe STMPS2262TTR contains two independent channels, which can either be operated separately or connected in parallel. The device is controlled by a Pulse Width Modulation (PWM) signal, which can be generated by an external microcontroller or logic chip. The control signal is used to adjust the on and off times of the distribution channels. Each channel has an integrated sense resistor that can detect current and voltage in real-time.When a channel is enabled, the PWM signal starts to regulate the switching frequency and duty cycle of the channel. The duty cycle is adjusted according to the current and voltage sensed by the integrated sense resistor. This ensures that the correct voltage and current are delivered to the load, which results in optimised power efficiency and reduced power losses.The STMPS2262TTR also offers over-temperature protection and over-current protection, which help ensure safe and reliable operation. The device can also be used for digital power management applications such as voltage sequencing, power fault control and remote monitoring.ConclusionSTMPS2262TTR from STMicroelectronics is a low-cost Power Distribution Switch, Load Driver that features robust current and voltage monitoring, over-temperature protection, over-current protection and a wide range of application flexibility.
