The TPS3307-18 is a micropower supply voltage supervisor designed for circuit initialization primarily in automotive DSP and processor-based systems, which require more than one supply voltage.

The TPS3307-18 is designed for monitoring three independent supply voltages: 3.3 V/1.8 V/adj,. The adjustable SENSE input allows the monitoring of any supply voltage >1.25 V.

The various supply voltage supervisors are designed to monitor the nominal supply voltage as shown in the following supply voltage monitoring table.

During power-on, RESET is asserted when the supply voltage V_DD becomes higher than 1.1 V. Thereafter, the supply voltage supervisor monitors the SENSEn inputs and keeps RESET active as long as SENSEn remain below the threshold voltage V_IT+.

An internal timer delays the return of the RESET output to the inactive state (high) to ensure proper system reset. The delay time, t_{d typ} = 200 ms, starts after all SENSEn inputs have risen above the threshold voltage V_IT+. When the voltage at any SENSE input drops below the threshold voltage V_IT–, the RESET output becomes active (low) again.

The TPS3307-18 incorporates a manual reset input, MR. A low level at MR causes RESET to become active. In addition to the active-low RESET output, the TPS3307-18 includes an active-high RESET output.
