TPS3839G25DBZR

超低功耗电源电压监控器 3-SOT-23 -40 to 85

The TPS3831 and TPS3839 devices both referred to as _TPS383x_ are ultralow current 150 nA, typical, voltage supervisory circuits that monitor a single voltage. Both devices initiate an active-low reset signal whenever the VDD supply voltage drops below the factory-trimmed reset threshold voltage. The reset output remains low for 200 ms typical after the VDD voltage rises above the threshold voltage and hysteresis. These devices are designed to ignore fast transients on the VDD pin. The TPS3831 device includes a manual reset input that forces RESET low when MR is low.

The ultralow current consumption of 150 nA makes these voltage supervisors ideal for use in low-power and portable applications. The TPS383x devices are specified to have the correct output logic state for supply voltages down to 0.6 V.

The TPS383x devices feature precision factory-trimmed threshold voltages and extremely low-power 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.
