Applications
TPS3779DQDBVRQ1 is designed for automotive ECU power-supply monitoring where strict voltage window compliance is required. It suits ADAS, infotainment, and body-control modules that need rapid fault detection across a 1.6 V to 5.5 V rail. The dual open-drain outputs enable direct connection to microcontroller reset pins without additional logic.

Frequently Asked Questions
What supply voltage range does TPS3779DQDBVRQ1 monitor, and how accurate are its thresholds?
TPS3779DQDBVRQ1 monitors supply voltages from 1.6 V to 5.5 V using two programmable window comparator thresholds that maintain 1% accuracy over the full -40°C to +125°C automotive temperature range, ensuring reliable fault detection in demanding environments.
How quickly does TPS3779DQDBVRQ1 respond to an out-of-window voltage event in an automotive ECU?
The device responds in as fast as 4.2 µs, asserting its open-drain reset outputs immediately when the monitored rail falls outside the programmed window. This rapid response protects microcontrollers and downstream ICs in ADAS and body-control modules before sustained overvoltage or undervoltage damage occurs.
What package is TPS3779DQDBVRQ1 available in, and how many pins does it have?
TPS3779DQDBVRQ1 is available in a 6-pin SOT-23 (DBV) package, offering a compact 1.6 mm × 2.9 mm footprint that conserves board space. The small outline makes it suitable for space-constrained automotive designs while still providing dual output pins for independent threshold signaling.
When is TPS3779DQDBVRQ1 preferred over a single-threshold supervisor for 3.3 V rail monitoring?
A window supervisor like TPS3779DQDBVRQ1 is preferred when both overvoltage and undervoltage faults must be detected independently on a 3.3 V rail, such as in automotive sensor interfaces where a ±5% window (3.135 V to 3.465 V) must trigger separate fault flags rather than a single reset signal.
