Working Principles

The TPS3851G30SQDRBRQ1 operates by continuously monitoring the input voltage levels. It compares these levels with the programmed threshold voltages set by the UV and OV inputs. If the voltage falls below the undervoltage threshold or exceeds the overvoltage threshold, the IC asserts the RESET output, indicating a fault condition. The RESET signal remains active until the voltage returns to the normal operating range.

The TPS3851G30SQDRBRQ1 is commonly used in various electronic systems that require voltage supervision. Some application fields include:

1. Automotive Electronics: Ensuring stable voltage levels in automotive control units, infotainment systems, and safety modules.
2. Industrial Automation: Monitoring power supply voltages in PLCs (Programmable Logic Controllers), motor drives, and industrial control systems.
3. Consumer Electronics: Providing voltage supervision in smart home devices, gaming consoles, and audio/video equipment.
4. Telecommunications: Ensuring reliable voltage levels in network switches, routers, and communication infrastructure.

Detailed and Complete Alternative Models

Some alternative models to the TPS3851G30SQDRBRQ1 include:
