STMPS2141STR

The part number STMPS2141STR corresponds to a high-side power switch IC (Integrated Circuit) manufactured by STMicroelectronics. High-side switches are commonly used in various electronic systems to control the power supply to loads such as motors, lamps, heaters, and other electrical devices.

Key Features:

• High-Side Power Switch: The STMPS2141STR is designed to control the power supply to loads connected on the high side of the circuit, enabling efficient switching and protection.

• Integrated Protection Features: The IC typically includes built-in protection features such as overcurrent protection (OCP), thermal shutdown, and overvoltage protection (OVP) to safeguard the load and the switch itself from damage due to fault conditions.

• Low RDS(ON): The on-resistance of the internal MOSFET transistor is typically low, minimizing power dissipation and voltage drop across the switch when it is in the ON state.

• Wide Input Voltage Range: The power switch IC may support a wide input voltage range, allowing it to be used in various applications with different supply voltages.

• Logic-Level Input Control: The switch is typically controlled by a logic-level input signal (e.g., from a microcontroller or digital circuit), allowing for easy interfacing and control.

• Fault Flag Output: Some high-side power switches feature a fault flag or status output pin that provides indication of any fault condition (e.g., overcurrent or thermal shutdown) detected by the device.

• Efficient Power Management: High-side switches help improve power management efficiency by providing a convenient means to control power distribution and manage load currents in electronic systems.

• Compact Package: The "STR" suffix in the part number indicates that the IC is provided in a surface-mount package, which offers compact size and ease of integration onto printed circuit boards (PCBs).

Applications:

• Automotive Electronics: Used in automotive systems such as body control modules, lighting systems, and power distribution units for switching loads such as lamps, motors, and solenoids.
• Industrial Control: Deployed in industrial automation and control systems for switching power to various loads such as pumps, valves, and actuators.
• Consumer Electronics: Found in consumer electronic devices such as white goods (e.g., washing machines, refrigerators) and home appliances for controlling power to motors, heaters, and other components.
• Telecommunications: Utilized in telecom infrastructure equipment, network switches, and routers for power distribution and load switching.
• LED Lighting: Integrated into LED lighting fixtures and systems for controlling power to individual LED strings or modules.
