For applications that require different values, contact your APPLICATIONS local TI representative. • CELL PHONE HANDSETS The OUT pin is a push-pull, active-high output. When • PORTABLE MEDIA PLAYERS the measured temperature is beyond the trip point • CONSUMER ELECTRONICS range of 0°C to +60°C (TMP303A), and the Set • SERVERS Output High (SOH) pin is low, the OUT pin is high. The SOH pin is an input pin with an internal pulldown • POWER-SUPPLY SYSTEMS resistor. When the SOH pin is forced high, the OUT • DC-DC MODULES pin goes high regardless of the measured • THERMAL MONITORING temperature. • ELECTRONIC PROTECTION SYSTEMS TMP303A/B HYSTERESIS SETTINGS DRL PACKAGE HYSTSET1 HYSTSET0 HYSTERESIS (°C) SOT563 (Top View) GND GND 1 GND VS 2 VS GND 5 VS VS 10 DEVICE SUMMARY DEVICE TRIP POINTS (°C) TMP303A TL = 0, TH = +60 (1) TMP303B TL = 0, TH = +55 (1) (1) Contact TI representative for other trip points. 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.
