Product Overview
The TPS3803 is a Texas Instruments voltage detector supervisor for Power_Management designs. It is supplied in a 5-pin SC-70 DCK package and supports recommended operation from 1.3 to 6 V, with input voltage specified from 0 to VDD + 0.3 V and an operating free-air temperature range of -40 to +85 °C.
For reset supervision, the TPS3803 uses an open-drain RESET output. Device threshold data includes the TPS3803-01 with a 1.226 V SENSE threshold and the TPS3803G15 with a 1.40 V VDD threshold. Related family data also lists TPS3805H33 thresholds of 3.05 V on VDD and 1.226 V on SENSE, with TPS3805 using a push/pull RESET output.
Electrical limits include +7 V absolute maximum supply voltage, -0.3 to +7 V on other pins, ±10 mA clamp current limits, and ±5 mA maximum output current ratings. Assembly and thermal data for the DCK package include +260 °C soldering temperature, 321 mW package power rating at TA below +25 °C, and derated ratings at +70 °C and +85 °C.
