SGLS143C – DECEMBER 2002 – REVISED DECEMBER 2015 TPS382x-xx-Q1 Voltage Monitor With Watchdog Timer
1 Features 3 Description 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 reset. The delay time, td, starts
after VDD has risen above the threshold voltage VIT-.
When the supply voltage drops below the threshold
voltage VIT-, the output becomes active (low) again.
No external components are required. All the devices …
