The Texas Instruments TPS3705-33DGNR is a microprocessor supply-voltage supervisor designed for circuit initialization and timing supervision in DSP and processor-based systems. It features a power-on reset generator with a fixed delay time of 200 ms, eliminating the need for external capacitors. The device offers precision supply voltage monitoring with a threshold voltage of 2.93V and can detect power-fail or low-battery warnings.
With a maximum supply current of 50 µA, this supervisor is suitable for battery-powered applications. It includes an integrated watchdog timer, enhancing system reliability. The TPS3705-33DGNR is pin-for-pin compatible with the MAX705 through MAX708 series and comes in an 8-pin MSOP package, suitable for surface mounting.
Applications for this supervisor IC include industrial equipment, programmable controls, automotive systems, intelligent instruments, wireless communication systems, and notebook or desktop computers. It ensures proper system initialization by asserting RESET when the supply voltage rises above 1.1 V and maintains RESET active as long as the supply voltage remains below the threshold.
