Product details

5V rail supervisor with adjustable timeout

It asserts an active-low, open-drain reset output when the monitored voltage drops below the 5V threshold. The reset timeout is adjustable via an external capacitor, giving the designer control over power-up and brown-out recovery timing without changing the supervisor part number.

Automotive-grade monitoring for under-hood environments

This part is qualified to AEC-Q100, making it suitable for automotive applications including engine control units, transmission controllers, and body electronics. The 10-VSON (3x3) package with exposed pad helps conduct heat to the PCB ground plane.

Open-drain output for system reset consolidation

The open-drain output allows multiple reset supervisors to share a common pull-up resistor, enabling a wired-OR configuration for system-level reset consolidation. This is useful when several voltage rails must be monitored and any one fault should trigger a global reset. The output is active-low, matching the reset polarity of most MCUs, DSPs, and FPGAs.

Frequently asked questions

Is TPS3850H50QDRCRQ1 AEC-Q100 qualified?

Yes, the TPS3850H50QDRCRQ1 is part of the Automotive, AEC-Q100 series, making it qualified for automotive applications.

What is the reset timeout of TPS3850H50QDRCRQ1?

The reset timeout is adjustable/selectable via an external capacitor, allowing the designer to set the delay between the supply crossing the threshold and the reset output de-asserting.

Can TPS3850H50QDRCRQ1 be used with an open-drain output?

Yes, the output is specified as Open Drain or Open Collector, active-low. This allows it to be pulled up to a different voltage than the monitored rail and to be wire-ORed with other open-drain outputs.
