TPS2065DBVR

The TPS2065DBVR is a power distribution switch, load driver and power monitor integrated circuit, which is designed to provide combined monitoring and control for low-voltage DC power distributed systems. It provides an integrated solution for current-limited and voltage-limited system applications. It is used in automotive and industrial systems, portable and computing applications. This IC includes two independent power switches, five overvoltage protections, five undervoltage protections and a current limit protection, with ± 5A and ± 60V limits, respectively.

The TPS2065DBVR is designed to provide clean and efficient power distribution, with low quiescent current, low on-resistance and low OFF leakage current. It has a regulated and continuous 2.5V current reference, which regulates the quiescent current levels during load switch ON time and standby mode. The integrated voltage sense interface provides supply voltage monitoring and overvoltage protection. The TPS2065DBVR also has an output enable switch, which is used to enable or disable the output of the main power switch.

The working principle of the TPS2065DBVR is relatively simple. When the supply voltage is between the upper and lower voltage thresholds, the system will be in normal operation mode. The power switches will be enabled and used to provide up to 5A of current. If the supply voltage is either above or below the predetermined set points, the TPS2065DBVR will enter over-voltage or under-voltage protection mode. In either of these cases, the power switches will be disabled to protect the system. Voltage and current protection levels can be programmed by the user through external resistors.

The TPS2065DBVR also provides an integrated power monitor, which allows for the monitoring of the supply voltage and current as well as a number of load-related parameters like consumption, temperature, current and peak current. With these built-in features, the TPS2065DBVR is an ideal solution for low-voltage DC power distributed systems. It offers reliable and safe power distribution, as well as integrated monitoring and control.
