The device asserts an active-low reset signal • Operating Supply Voltage: 0.6 V to 6.5 V whenever the VDD supply voltage drops below the factory-trimmed reset threshold voltage. The reset • Ensured Valid RESET for VDD > 0.6 V output remains asserted for 200 ms (typ) after the • Push-Pull RESET Output VDD voltage rises above the threshold voltage. The • Temperature Range: –40°C to +85°C TPS3839 is designed to ignore fast transients on the VDD pin. • Factory-Trimmed RESET Threshold Voltages The ultra-low current consumption of 150 nA makes APPLICATIONS the TPS3839 ideal for use in low-power and portable applications. The TPS3839 is ensured to have the • Portable and Battery-Powered Equipment correct output logic state for supply voltages down to • Industrial Equipment 0.6 V. • Cell Phones The device features precision factory-trimmed • Glucose Monitors threshold voltages and extremely low power • Metering operation. The TPS3839 is available is a 3-pin SOT23 (DBZ) package or a 4-pin 1-mm × 1-mm • Televisions (DQN) µSON 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.
