Product Overview
The TPS3899_Voltage-Supervisor is a Texas Instruments precision voltage supervisor for Power_Management designs. It is supplied in a DSE WSON-6 package with a 1.5 mm x 1.5 mm body, supporting compact assembly where the listed thermal resistance is 214.9 °C/W for the DSE 6-pin package.
The device provides multiple reset output configurations: DL open-drain active-low, PL push-pull active-low, and PH push-pull active-high. Recommended operating conditions include 0-6 V on VDD and SENSE, 0 V to VDD on CTR and CTS, and 0 to ±5 mA RESET pin current. The DL and PL output options support a 0.85-6 V VDD range, while the PH output option supports 1-6 V.
Threshold options include a 0.505 V adjustable sense threshold and fixed thresholds from 0.8 V to 5.4 V in 100 mV steps. Timing behavior is supported through CTR and CTS pins, each with a 0-10 µF recommended capacitor range, 0.73 x VDD threshold voltage, and 500 kΩ typical internal pull-up resistance.
