Texas Instruments NANOPOWER HIGH-INPUT VOLTAGE SUP TPS3840PL33DBVR

The TPS3840PL33DBVR is an adjustable precision supervisory circuit with low-power consumption, high accuracy, and fast response time. It monitors system power supplies and asserts a reset signal to microprocessors or digital circuits when the supply voltage drops below a preset threshold (2.93V typical). This device also features a manual reset input, a watchdog timer, and an open-drain output. It operates over a wide temperature range (-40°C to +125°C) and comes in a small 6-pin SOT-23 package making it ideal for use in various applications including industrial systems, communication equipment, and portable devices.
