TPS3803-01DCKR General Description
The TPS3803-01DCKR is a part of the TPS3803 and TPS3805 families of supervisory circuits, specifically designed for providing circuit initialization and timing supervision for DSPs and processor-based systems. With its fixed-sense threshold voltage and adjustable SENSE input, it offers flexibility in configuration based on the application's requirements. The device ensures that RESET is asserted during power-on and remains active as long as the supply voltage or SENSE input remains below the threshold voltage. Once the voltage rises above the threshold, RESET is deasserted, indicating normal operation. The product spectrum caters to various supply voltages, including 1.5V, 3.3V, and adjustable options, making it versatile for different system designs. Packaged in a 5-pin SC-70 package, the TPS3803-01DCKR is a compact and efficient solution for system initialization and monitoring. It operates reliably over a wide temperature range of -40°C to +85°C, making it suitable for diverse environmental conditions and applications
Features
- This IC has a threshold voltage of 3.08V with a typical operating range of 2.7V-10V
- Features integrated watchdog timer and manual reset input for system monitoring
- Low power consumption makes it suitable for portable devices
- A compact SOT-23 package allows for easy integration into circuit designs
