DUAL PROCESSOR SUPERVISORS

Dual Supervisory Circuits for DSP- and
The TPS3305 family is a series of micropower supply
Processor-Based Systems
voltage supervisors designed for circuit initialization.
Its dual monitor topology is well-suited to use in DSP
Power-On Reset Generator with Fixed Delay
and processor-based systems, which often require
Time of 200ms; no External Capacitor Needed
two supply voltages, core and I/O.
Watchdog Timer Retriggers the RESET Output
RESET is asserted when the voltage at either
at SENSEn
≥ VIT+
SENSEn pin falls below its threshold voltage, VIT.
Temperature-Compensated Voltage Reference
When both SENSEn pins are again above their
Maximum Supply Current of 40A
respective threshold voltages, RESET is held low for
the factory-programmed delay time (200ms typ).
Supply Voltage Range: 2.7V to 6V
RESET is also asserted if the watchdog input (WDI)
Defined RESET Output From V
DD ≥ 1.1V
is not toggled for more than 1.6s typ.
MSOP-8 and SO-8 Packages
The TPS3305-xx devices are available in either 8-pin
Temperature Range: –40°C to +85°C
MSOP or SO packages, and are specified for
operation over a temperature range of –40
°C to
+85
°C.
