5 V, 3 V, 3.
3 V, 5 V • Watchdog timer (TPS3820/3/4/8-xx-Q1) • Supply current of 15 μA (Typical) • 5-Pin SOT-23 package • Temperature range: −40°C to 125°C 2 Applications • Automotive DSPs, microcontrollers, or microprocessors • Industrial equipment • Programmable controls • Automotive systems • Portable and battery-powered equipment • Intelligent instruments • Wireless communications systems 3 Description For all new designs with TPS3820-xx-Q1, use the TPS3820-xxQPDBVRQ1 part number.
The TPS3820xxQP is functionally equivalent and a replacement to the TPS3820xxQ.
The TPS3820-xxQDBVRQ1 is not recommended for new designs (NRND).
The TPS382x-xx-Q1 family of supervisors provide circuit initialization and timing supervision, primarily for DSP and processor-based systems.
During power on, RESET asserts when the supply voltage VDD becomes greater than 1.
1 V.
Thereafter, the supply voltage supervisor monitors VDD and keeps RESET active low as long as VDD remains below the threshold voltage, VIT−.
An internal timer delays the return of the output to the inactive state (high) to ensure proper system rese...
