Both devices assert 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 asserted for 200 ms (typical) after the • Temperature Range: –40°C to +85°C VDD voltage rises above the threshold voltage. These devices are designed to ignore fast transients on the • Packages: 1-mm × 1-mm X2SON or 3-Pin VDD pin. Note that the TPS3831 includes a manual SOT23 reset input. APPLICATIONS The ultralow current consumption of 150 nA makes these voltage supervisors ideal for use in low-power • Portable and Battery-Powered Equipment and portable applications. The TPS383x are specified • Industrial Equipment to have the correct output logic state for supply • Cell Phones voltages down to 0.6 V. • Glucose Monitors The TPS383x feature precision factory-trimmed • Metering threshold voltages and extremely low-power operation. The TPS3831 is available is a 4-pin 1-mm • Televisions × 1-mm (DQN) X2SON package. The TPS3839 is available in a 3-pin SOT23 (DBZ) package or a 4-pin 1-mm × 1-mm (DQN) X2SON package. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
