The TPS3850H01DRCR is a highly precise voltage supervisor with a programmable window-watchdog timer, designed and manufactured by Texas Instruments. This integrated circuit (IC) is engineered to monitor voltage rails that require tight accuracy and timing to ensure proper system functionality.

Key Features

• Voltage Supervision: The TPS3850 features a combination of overvoltage and undervoltage monitors, ensuring that the system operates within its specified voltage range. This is critical for preventing damage to sensitive electronic components.
• Programmable Window-Watchdog Timer: This feature allows for the detection of software anomalies and malfunctions. If the watchdog is not serviced within a programmed time window, the device will trigger a system reset, ensuring reliable operation and recovery from fault states.
• High Accuracy: The TPS3850 offers a high threshold accuracy of ±0.8% over the full temperature range, which is essential for systems that depend on precise voltage levels for optimal performance.
• Adjustable Thresholds: The device allows users to set custom voltage thresholds via external resistors, providing flexibility across different applications and design requirements.
• Power-On Reset (POR) Delay: The IC includes a programmable delay time for the power-on reset signal, allowing the system to stabilize before normal operation commences.

Applications

The TPS3850H01DRCR is ideal for a wide range of applications where voltage monitoring and system reliability are paramount. These include:

• Industrial control systems
• Automotive electronics
• Telecommunications equipment
• Enterprise servers
• Medical devices
