The TPS2065CDGNR-2 is a high-performance, low-RDS(on) Power Distribution Switch (PDS) Load Driver from Texas Instruments. The device is a one-channel, intelligent power distribution switch, equipped with a micro-controller unit (MCU) for high-power applications. It is designed to deliver up to 55 amps at up to 40 volts, and can be used in a variety of different applications such as automotive and industrial.

The TPS2065CDGNR-2 combines the flexibility of an MCU with the efficiency of a low-RDS(on) power switch, enabling it to be used in a wide range of applications. This allows users to power multiple devices without being limited to any particular configuration or protocol. The device also offers configurable over-current protection and over-temperature protection.

The device is controlled by an on-chip MCU, which features user-programmable settings for current limit, over-current protection, thermal limit, and fault indications. The chip allows for thermal and over-current protection thresholds to be set, as well as for sleep modes to be implemented for improved power savings. Additionally, it has the capability to interface with an external data bus for additional control.

The working principle of the TPS2065CDGNR-2 is simple and straightforward. It features a one-channel, low-RDS(on) power switch, which is controlled by the on-chip MCU. The device is designed to operate in two modes: stand-alone or under remote control. In stand-alone mode, the device is simply driven by the voltage applied at its gate pin. Alternatively, in remote control mode, the device is driven by an external micro-controller or data bus.

When the device is activated, it will sense the current through the load and adjust the duty cycle to maintain the desired power limit. If the sensed current exceeding the limit, it will automatically turn off the power switch. The device can also be used to detect over-current conditions and respond accordingly by disabling the switch or initiating a reset.

Despite its small size, the TPS2065CDGNR-2 is a highly capable and versatile Load Driver for a range of applications. It offers a reliable and cost-effective way to power multiple devices in high-power applications such as automotive and aerospace. Additionally, its programmable features enable it to be used with a range of different protocols and applications.
