3 / 19 page LM3722, LM3723, LM3724 www.ti.com SNVS154E – MAY 2001 – REVISED MARCH 2013 These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. Absolute Maximum Ratings (1) (2) VCC, MR −0.3V to 6.0V RESET, RESET −0.3V to (VCC+ 0.3V) Input Current, VCC Pin 20mA Output Current, RESET, RESET Pin 20mA ESD Rating (3) 2kV Continuous Power Dissipation (TA = +70°C) SOT-23 (4) 320mW Operating Temperature Range Industrial: −40°C to +85°C Extended: −40°C to +125°C Maximum Junction Temperature 125°C Storage Temperature Range −65°C to +160°C Lead Temperature (soldering, 10sec) +300°C (1) Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which the device operates correctly. Operating ratings do not imply guaranteed performance limits. For guaranteed performance limits and associated test conditions, see the Electrical Characteristics. (2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and specifications. (3) The human body model is a 100pF capacitor discharged through a 1.5k Ω resistor into each pin. (4) At elevated temperatures, devices must be derated based on package thermal resistance. The device in the SOT-23-5 package must be derated at 4.5mW/°C at ambient temperatures above 70°C. The device has internal thermal protection. Electrical Characteristics Typical values are at TA = +25°C. Limits with standard typeface are for TA = +25°C, and limits in boldface type apply for the operating temperature range ( −40°C to +85°C) for LM372_IM5X, and (−40°C to +125°C) for LM372_EM5X, unless otherwise noted.

Limits over the operating temperature range are guaranteed through correlation using Statistical Quality Control (SQC) methods. (2) RESET Output for LM3722 and LM3724, RESET output for LM3723. (3) Glitches of 100 ns or less typically will not generate a reset pulse.
