TPL7407LADR

The TPL7407LADR is a Power Distribution Switch, Load Driver, an integrated circuit (IC) used in a variety of applications. It is utilised in motor control applications, such as motor control relays, as well as general purpose signal routing and signal amplification. The IC features a wide voltage range, low UVLO and current drive capability, and high immunity to RF interference.

The TPL7407LADR combines a level-shift driver, power distribution switch, and load driver in a single device. It features dual outputs, with each output capable of providing up to 5A in continuous mode, and as much as 10A in peak current mode. The device also features an independent error flag that indicates an output current that exceeds 5A, which helps reduce risk of overloading the device.

The power distribution switch of the TPL7407LADR is achieved via two MOSFETs. When the input voltage is applied, one MOSFET provides a connection between the two outputs, while the other MOSFET provides a connection between the two inputs. The input/output connections are controlled by the logic signals applied to the TPL7407LADR\'s control pins.

The TPL7407LADR also includes a level-shift driver, allowing it to operate with voltages as high as 500Vdc. This makes the device ideal for applications in which the load may require up to 500Vdc. Additionally, the device features low-voltage operation (3V minimum).

The device also features a current-limit circuitry, designed to prevent damage to the device due to large input currents. The current-limit circuitry is enabled when the voltage is applied, and will automatically shut off the circuit if the input current exceeds a predetermined threshold. This prevents overloading of the device and helps prevent damage.

The device also includes a thermal-control circuit, which ensures optimal operation at all temperatures. The thermal-control circuit monitors the temperature of the IC, and dynamically adjusts the voltage and current operating levels in order to ensure the device does not overheat.

The TPL7407LADR is designed to operate with a wide range of input and output voltages, up to 500V. This makes the device suitable for many different applications, including automotive and industrial motor control, as well as general purpose signal routing and amplification. The device\'s wide voltage range and high immunity to RF interference makes it an ideal choice for these types of applications.
