The TLV8x3 family of supervisory circuits provides circuit initialization and timing supervision, primarily for DSPs and processor-based systems.

The TLV803, TLV853, and TLV863 are functionally equivalent. The TLV853 and TLV863 provide an alternate pinout of the TLV803. The newer TLV803E device is a pin-to-pin alternative to all of these 3.

During power on, RESET asserts when the supply voltage (V_DD) exceeds 1.1 V. Thereafter, the supervisory circuit monitors V_DD and keeps RESET active as long as V_DD remains below the threshold voltage V_IT. An internal timer delays the return of the output to the inactive state (high) to ensure proper system reset. The delay time (t_d(typ) = 200 ms) starts after V_DD exceeds the threshold voltage, V_IT. When the supply voltage drops below the V_IT threshold voltage, the output is active (low) again. All the devices in this family have a fixed sense-threshold voltage (V_IT) set by an internal voltage divider.

The product spectrum is designed for supply voltages of 2.5 V, 3 V, 3.3 V, and 5 V. These devices are available in a 3-pin SOT-23 package. The TLV803 devices are characterized for operation over a temperature range of –40°C to +125°C.
