Key Features
- Automotive-qualified voltage supervisor with manual reset pin for controlled system restart in AEC-Q100 environments
- Programmable reset time delay allows customizable hold-off period to prevent false resets during transient supply events
- High-input voltage capability in a compact 5-pin SOT-23 (R-PDSO-G5) package ideal for automotive ECU and body control modules
Applications
The PTPS3840PH27DBVRQ1 is designed for automotive electronic control units (ECUs), body control modules, and ADAS subsystems that require reliable voltage supervision over a wide input voltage range. The programmable reset delay ensures microcontrollers and processors are held in reset long enough for power rails to fully stabilize before boot-up. Its manual reset input provides a hardware override for safety-critical systems requiring deterministic reset behavior.

Frequently Asked Questions
What makes the PTPS3840PH27DBVRQ1 suitable for automotive applications?
The PTPS3840PH27DBVRQ1 is automotive-grade and meets AEC-Q100 qualification requirements. It is designed to operate reliably under the wide voltage transients and temperature extremes typical of automotive 12V and 24V electrical systems, making it suitable for ECUs, body control modules, and infotainment systems.
What does the programmable reset time delay feature do?
The programmable reset time delay allows designers to set a specific hold-off period after a power supply undervoltage event before releasing the reset signal. This ensures that all power rails have fully stabilized before the connected microcontroller or processor attempts to boot, preventing corrupted initialization sequences.
Does the PTPS3840PH27DBVRQ1 have a manual reset input?
Yes, the PTPS3840PH27DBVRQ1 includes a manual reset input pin that allows an external signal or button to force a system reset independently of supply voltage conditions. This is important for service, diagnostics, and safety-critical reset scenarios in automotive and industrial applications.
What package and pin count does the PTPS3840PH27DBVRQ1 use?
The PTPS3840PH27DBVRQ1 is housed in a 5-pin SOT-23 plastic package (JESD-30 code R-PDSO-G5). This small surface-mount package conserves board space and is easy to place near the power input or microcontroller reset pin in tight PCB layouts.
