The Texas Instruments TPS3705-30DR is a microprocessor supply voltage supervisor designed to provide circuit initialization and timing supervision. It features a power-on reset generator with a fixed delay time of 200 ms, eliminating the need for external capacitors. The device precisely monitors supply voltages, with a specific threshold of 2.63V for this variant, and asserts RESET when the supply voltage drops below this level.
This supervisor includes a voltage monitor for power-fail or low-battery warnings and an integrated watchdog timer for enhanced system reliability (specific to TPS3705-xx models). It operates with a maximum supply current of 50 µA, making it suitable for low-power applications. The TPS3705-30DR is available in an 8-pin SOIC package and operates over a temperature range of -40°C to 85°C.
Applications for the TPS3705-30DR include designs using DSPs, microcontrollers, and microprocessors, as well as industrial equipment, programmable controls, automotive systems, and portable or battery-powered devices. Its pin-for-pin compatibility with the MAX705 through MAX708 series offers an easy upgrade path for existing designs.
