TPS3806J20DBVR

The TPS3806J20DBVR is a voltage supervisor used in power management integrated circuits (PMICs). It is capable of high current load sensing and can be used to set an adjustable over-voltage point. It is designed to provide an accurate, programmable over-voltage and under-voltage protection threshold.

The TPS3806J20DBVR is the latest generation of precision dual-channel voltage supervisors from Texas Instruments. The device has been designed to provide circuit protection and power go/no-go testing in a variety of end-equipment applications. It has a wide operating temperature range (-40°C to +125°C), and can be operated from a single 3V supply.

The TPS3806J20DBVR has two channels: each capable of monitoring a separate voltage. The supply voltage for the supervisor can be between 1.7V and 5.5V. A single 3V supply can be used to monitor two voltages of 4.5V and 2.6V, or one voltage of 4.5V. Monitoring two voltages can be accomplished by setting the voltage threshold of the second channel to the same as the first channel. The device features a 10-bit digital power-on reset (POR) threshold adjustment, with a wide adjustment range of 1V to 5.1V.

The device also has an adjustable power-on reset (POR) timeout period, which can be set between 1 ms and 65 ms. The POR timeout period is programmable and allows the device to remain in POR mode until the monitored voltage reaches the programmed threshold. The POR timeout period is adjustable in increments of 7.8125 ms, allowing for precision control of the POR time. The device also has an internal counter which prevents multiple POR events from occurring within a single POR timeout period.

The TPS3806J20DBVR also features programmable over-voltage and under-voltage thresholds. The device has an adjustable over-voltage threshold of up to 3.2V, and a minimum under-voltage threshold of 0.0625V. The device also has a built-in soft-start circuit, which prevents the output from exceeding the maximum over-voltage or minimum under-voltage threshold, even during power-up.

The device has an open-drain output signal, which is used to indicate an over-voltage or under-voltage condition. The device also has a logic reset signal, which is used to reset the device following an over-voltage or under-voltage event. The device has an active-low output polarity, with an output voltage of 0V when in reset. Lastly, the device has two enable pins, which are used to enable the two channels of the device.

The TPS3806J20DBVR is ideal for portable electronics and is suitable for use in a wide range of applications, including digital cameras, PDAs, mobile phones, and other consumer electronics. It can also be used in automotive and industrial applications, specifically in applications such as over-voltage and under-voltage protection, power-on reset delay and precision sensing of high-current loads. The device is suitable for use in applications where accuracy, reliability and safety are of utmost importance.
