The TPS3803 and TPS3805 families of supervisory

circuits

provide

circuit

initialization

and

timing

supervision, primarily for DSPs and processor-based

systems.

The TPS3803G15 device has a fixed-sense threshold

the TPS3803-01 has an adjustable SENSE input that

can be configured by two external resistors. In

addition to the fixed sense threshold monitored at

adjustable SENSE input. RESET is asserted in case

During power on, RESET is asserted when supply

RESET is deasserted again. The product spectrum is

designed for 1.5 V, 3.3 V, and adjustable supply

voltages.

The devices are available in a 5-pin SC-70 package.

The

TPS3803

and

TPS3805

devices

are

characterized for operation over a temperature range

of –40

°C to 125°C.
