TPS3825-33DBVT

TPS3825-33DBVT Description

The TPS3825-33DBVT from Texas Instruments is a high-performance, single-channel voltage supervisor designed for precision monitoring of power supply rails in embedded systems. Housed in a compact SOT23-5 package, this supervisor IC ensures reliable system operation by generating a reset signal when the monitored voltage falls below the fixed threshold of 2.93V. With a 120ms minimum reset timeout, it provides ample time for microcontrollers or processors to stabilize during power-up or brownout conditions. The device is ROHS3 compliant, REACH unaffected, and features a moisture sensitivity level (MSL) of 1 (Unlimited), making it suitable for industrial and automotive applications.

TPS3825-33DBVT Features

• Fixed Threshold Voltage (2.93V): Ensures precise monitoring for 3.3V systems.
• Active High Reset Output: Simplifies integration with microcontrollers requiring active-high reset signals.
• 120ms Minimum Reset Timeout: Guaranteed delay for stable system initialization.
• Surface-Mount SOT23-5 Package: Space-efficient for compact PCB designs.
• Wide Operating Range: Suitable for harsh environments with robust performance.
• Low Power Consumption: Ideal for battery-powered applications.
• RoHS3 & REACH Compliant: Meets stringent environmental and safety standards.

TPS3825-33DBVT Applications
