TPS3836L30MDBVREP

Power management integrated circuits (PMICs) are integrated circuits (ICs) that are primarily used to manage power supply in an electronic system. PMICs are used in a variety of applications, ranging from telecommunications to automotive systems. One particular type of PMIC is a supervisor, which is used to protect the system from damage due to faults, voltage spikes, and over-current conditions. The TPS3836L30MDBVREP is a supervisor device from Texas Instruments that is designed for fault protection and power supply sequencings in a variety of applications, such as automotive, industrial, and communications systems.

Functionality & Features

The TPS3836L30MDBVREP is a precision micro-power supervisory circuit that works as a voltage monitoring device. It features an adjustable and precise reset pulse width and delay time, as well as a power-on-reset (POR) timer that monitors system power-up sequences. The device is able to detect a wide range of voltage levels (down to 0.75 V), and includes an open-drain, active-low NRST reset output. Additionally, the device includes a watchdog timer (WDT) that can be enabled with an active-low WDI input. The WDT features an adjustable timeout period between 1.6 ms and 838 seconds in typical applications.

The device also features an enable (EN) input that can be used to disable the WDT, or enable an alternate function. When enabled, the enable function provides the RST and WDI outputs with low peak current during an assertion. This feature is often used to conserve power by disabling the reset during the absence of a fault. The device also features a short circuit current limitation, allowing the TPS3836L30MDBVREP to be deployed in systems with high capacitive loads.

Applications

The TPS3836L30MDBVREP is ideal for a variety of fault protection and power sequencing applications. It can be used to protect systems against over-voltage, under-voltage, and over-current conditions, as well as to monitor power-up sequences. It is suitable for applications in the automotive, communications, industrial, and computing markets, where precise monitoring and protection against fault conditions is required.

TPS3836L30MDBVREP is an ideal solution for car electronics system that require precise voltage monitoring and reset functions. It is also suitable for top-level power supplies in industrial and communications systems, as it is able to detect a wide range of voltage levels and can protect against over-current conditions. The wide range of time-outs on the watchdog timer make it suitable for a variety of sequencings applications.

Conclusion

The TPS3836L30MDBVREP is an advanced supervisor device from Texas Instruments that is used for fault protection and power sequencing. It features adjustable and precise reset pulses, a power-on-reset timer, a watchdog timer, and a low peak-current enable input. The device is suitable for automotive, communications, industrial, and computing applications, where it can be used to protect the system from faults, and to sequence power-up steps.
