Integrated supply-voltage supervisor and watchdog timer in SOT-23 package

Texas Instruments new TPS3823-xx and TPS3824-xx microprocessor supervisory circuits combine precision supply voltage monitoring with a watchdog timer and a manual reset.

These devices interface with the TMS320C54x and are well suited for cell phones, portable battery-powered equipment and DSP monitoring. They are the only fixed 2.5-V supervisors available in a micro-sized SOT-23 package. The TPS3823 offers a manual reset input, while the TPS3824 features a high-level reset output.

The RESET output is guaranteed asserted when VDD reaches 1.1 V eliminating undefined states during power-up. After supply voltages reach operating thresholds, a fixed reset delay time of 200 ms ensures that the supply has stabilized and the system has been properly reset before processor operation is allowed. Reset thresholds are guaranteed to 2 percent accuracy.

Product features

  • 2.5-V, 3.0-V, 3.3-V and 5.0-V options
  • Fixed delay time of 200 ms
  • Watchdog timer
  • No external components required
  • 25-µA supply current max
  • Characterized for operation from 40°C to 85°C
