DCK PACKAGE (TOP VIEW) GND 1 GND 2 These devices assert a push-pull RESET signal when the SENSE (adjustable version) or VDD (fixed version) drops below a preset threshold. The RESET output remains asserted for the factory programmed delay time after the SENSE or VDD return above its threshold. The TPS380x devices, except the TPS3801-01, incorporate a manual reset input (MR). A low level at MR causes RESET to become active. The TPS380x uses a precision reference to achieve an overall threshold accuracy of 2% - 2.5%. These devices are available in a 5-pin SC-70 package, which is only about half the size of a 5-pin SOT-23 package. The TPS380x devices are fully specified over a temperature range of -40°C to 85°C. typical applications VDD = 1.8 V 5 MR 100 nF VDD RESET 3 4 VDD GND 1 GND 2 RESET 3 5 SENSE 4 VDD TMS320VC5420 TPS3801E18 MR TPS3801−01 . . .
