Both devices initiate an active-low reset signal whenever the VDD supply voltage drops below • Push-Pull RESET Output the factory-trimmed reset threshold voltage. The reset • Factory-Trimmed Reset Threshold Voltages output remains low for 200 ms (typical) after the VDD • Temperature Range: –40°C to 85°C voltage rises above the threshold voltage and hysteresis. These devices are designed to ignore fast • Packages: 1-mm × 1-mm X2SON or 3-Pin SOT23 transients on the VDD pin. The TPS3831 device includes a manual reset input that forces RESET low 2 Applications when MR is low. • Portable and Battery-Powered Equipment The ultralow current consumption of 150 nA makes • Metering these voltage supervisors ideal for use in low-power • Industrial Equipment and portable applications. The TPS383x devices are • Cell Phones specified to have the correct output logic state for supply voltages down to 0.6 V. • Glucose Monitors The TPS383x devices feature precision factory- • Tablets trimmed threshold voltages and extremely low-power • Wearables operation. The TPS3831 device is available in a 4- pin, 1-mm × 1-mm (DQN) X2SON package. The TPS3839 device is available in a 3-pin SOT23 (DBZ) package or a 4-pin, 1-mm × 1-mm (DQN) X2SON package.
