The Texas Instruments TPS3850G50DRCT is a member of the TPS385 family of supervisors which combines the low voltage (200mV maximum) supervisor latch and reset generator. This device monitors the power supply voltage of a system and triggers a reset pulse in case of voltage fluctuation or an under voltage event. It is designed to help protect the system from a power surge or temporary power loss. The device has a wide range of operating temperatures, from -40°C to +85°C, and is packaged as an SOIC (Small Outline Integrated Circuit). The TPS3850G50DRCT is a low power supervisor designed for applications where space is limited.

The TPS3850G50DRCT offers a reset time of 10ms and monitors 1.8V to 13.2V power supply. Additionally, it supports various reset methods such as, active low reset output and manual reset input for added flexibility and control. The device is also equipped with an open drain watchdog to support an auto-reset from an external source in case of system failure. Additionally, the device has an integrated voltage supervisor that latches upon activation and keeps the reset active until the voltage is restored, thereby providing extra protection from system failure.

The TPS3850G50DRCT is a widely utilized supervisor IC for a variety of applications in both consumer electronics and industrial systems. It is typically used to monitor power levels in system boards, and to minimize the probability of system failure by detecting unexpected power supply fluctuations or loss. The device is also widely used in circuit design and development to test various power supplies and configurations.

In applications such as industrial controllers, medical and military equipment, the TPS3850G50DRCT can be used as an external device, or as an integrated part of the circuit. It is used to protect against unexpected power failures, and to ensure components remain in their expected operating state, thus keeping the system operating without any unexpected issues.

The working principle of the TPS3850G50DRCT is simple and effective. The IC monitors the power supply voltage of the system, generating a reset pulse in case of voltage fluctuation or an under voltage event. This reset pulse is then used by the circuit to restore the components and to resume system operations. Additionally, the IC is designed to self-adjust its reset threshold level when the system is powered on, thereby providing additional protection against voltage fluctuations.

The TPS3850G50DRCT is an ideal choice for applications that require a low voltage, small form factor supervisor with a wide operating temperature range. Its versatile reset generator and voltage supervisor makes it a popular choice for applications requiring reliable power monitoring and protection.
