Product Overview
The TPS3899 is a Texas Instruments precision voltage supervisor in the Power_Management category. It is offered in a compact DSE WSON-6, 1.5 mm x 1.5 mm package and supports voltage supervision using either an adjustable 0.505 V typical sense threshold or fixed threshold options from 0.8-5.4 V in 100 mV steps.
Supply support depends on the output variant: DL and PL versions operate from 0.85-6 V, while the PH version operates from 1-6 V. The device specifies 125 nA typical VDD pin current under the listed 6 V test condition, with recommended VDD and SENSE voltages of 0-6 V. CTR and CTS pins are recommended from 0 V to VDD, with capacitor ranges of 0-10 µF.
Output configurations include TPS3899DL open-drain active-low with a required pull-up resistor, TPS3899PL push-pull active-low, and TPS3899PH push-pull active-high. The operating free-air temperature range is -40°C to +125°C, with DSE 6-pin junction-to-ambient thermal resistance specified at 214.9°C/W.
