TPS3701DDCR | TI window voltage detector, 36V 24V rail monitoring IC
The TPS3701DDCR is a Texas Instruments ACTIVE 36V voltage detector, a high-voltage window comparator and TI window voltage detector for one-rail UV/OV protection or two independent monitors. It runs from 1.8 V to 36 V at -40 C to +125 C, draws 7 uA typical, and uses a 2.9 x 1.6 mm SOT-23-THN (DDC-6) package. Two precision comparators use an internal 400-mV reference; 25-V-rated open-drain OUTA/OUTB assert low on INA undervoltage or INB overvoltage. A three-resistor divider sets adjustable thresholds down to 400 mV, with 0.75% accuracy over temperature, 0.25% typical, 5.5 mV hysteresis and 28.1 us maximum propagation delay. This SOT-23-THN voltage supervisor is also an adjustable threshold voltage detector, open-drain output supervisor and low quiescent current supervisor that replaces discrete comparator chains.
Key Features & Applications
● 1.8 V to 36 V VDD plus separate sense pins; the monitored rail may differ from the supply.
● Dual 400 mV internal reference comparator channels, 0.75% over temperature and 0.25% typical.
● Two 25 V active-low open-drain outputs; wired-OR gives one combined fault flag.
● 5.5 mV hysteresis rejects noise and chatter at trip points.
● 7 uA typical/11 uA max Iq, 28.1 us max propagation delay, no delay or watchdog.
●  Catalog -40 C to +125 C, RoHS/REACH, NiPdAu and MSL Level-2-260C-1 YEAR.
● Window detector or two independent monitors with resistor-set UV/OV thresholds.
This overvoltage undervoltage monitor is a 24V rail monitoring IC for PLCs, factory automation, 12 V/24 V supplies, servo drives and analog I/O modules. It also protects DSP, MCU, FPGA and ASIC rails, embedded computing, battery products, telecom hardware and power-path multiplexers. TI's TIDA-00396 demonstrates a 24 V window monitor under 20 uA.
FAQs
Q: Pull-ups? Yes, open-drain outputs need pull-ups to 3.3 V/5 V logic within the 25 V rating.
Q: Reset delay? No, TI lists 0 ms; use an RC network or TPS37/TPS3703 for controlled delay.
Q: Combined fault? Yes, tie outputs together for wired-OR, or separate them for UV/OV diagnosis.
