DCK PACKAGE (TOP VIEW) description The TPS380x family of supervisory circuits provide circuit initialization and timing supervision, primarily for DSPs and processor-based systems. During power-on, RESET is asserted when the supply voltage VDD becomes higher than 1.1 V. Thereafter, the supervisory circuit monitors VDD (or SENSE) and keeps RESET active as long as VDD (or SENSE) 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 (or SENSE) 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 of this family have a fixed sense-threshold voltage (VIT) set by an internal voltage divider, except for the TPS3801-01, which can be customized with two external resistors at the SENSE input. The TPS380x devices, except the TPS3801-01, incorporate a manual reset input (MR). A low level at MR causes RESET to become active. GND 1 GND 2 RESET 3 5 MR 4 VDD TPS3801-01 . . .

The circuits are available in a 5-pin SC-70 (SOT-323) package, which is only about half the size of a 5-pin SOT-23 package. GND The TPS3801-01 can monitor voltages as low as 1.14 V, depending on the configuration of the external resistor divider. The TPS380x devices are characterized for operation over a temperature range of -40C to 85C.
