The TPS3705-50DGN from Texas Instruments is a microprocessor supply-voltage supervisor designed for circuit initialization and timing supervision. It provides a power-on reset generator with a fixed delay time of 200 ms, eliminating the need for external capacitors. This device monitors a single supply voltage and asserts a reset when the voltage drops below a threshold, with an active-low, push-pull output.
Key electrical characteristics include a 4.55V monitoring threshold and a reset timeout of 140ms minimum. The device operates over a temperature range of -40°C to 85°C. It is pin-for-pin compatible with the MAX705 through MAX708 series and is available in an 8-pin MSOP package.
Applications for the TPS3705-50DGN include designs using DSPs, microcontrollers, or microprocessors, industrial equipment, programmable controls, automotive systems, and portable or battery-powered equipment. Its integrated watchdog timer (on TPS3705-xx variants) and power-fail warning capabilities make it suitable for robust system designs.
