Ultra-Low Power Voltage Supervisor IC with Open-Drain Reset Output for Reliable Power Supply Monitoring
The TPS3897ADRYR is a high-precision voltage supervisor designed to monitor system supply rails and provide reliable reset functionality in microcontroller and processor-based systems. Developed by Texas Instruments, this device detects undervoltage conditions and asserts a reset signal to prevent incorrect operation when the supply voltage falls below the defined threshold.
This supervisor features an open-drain reset output that allows flexible integration with different logic voltage levels using an external pull-up resistor. The TPS3897 series is known for its ultra-low quiescent current, making it particularly suitable for battery-powered devices and energy-efficient embedded systems. Its compact SON-6 package ensures minimal PCB footprint, making it ideal for portable electronics, industrial controllers, IoT hardware, and space-constrained applications.
