The maximum input voltage that can be applied to the TPS2080DR is 5.5V, as specified in the datasheet. Exceeding this voltage may damage the device.
To ensure proper power-up and configuration, follow the recommended power-up sequence: 1) Apply input voltage (VIN) to the device, 2) Wait for the internal voltage regulator to stabilize (typically <10ms), and 3) Configure the device using the EN and ILIM pins.
The EN pin is an active-high enable input that allows the device to be turned on or off. When EN is high, the device is enabled, and when EN is low, the device is disabled. Use the EN pin to control the power state of the device, such as in power-saving modes or during system shutdown.
The current limit (ILIM) is set using an external resistor (RILIM) connected between the ILIM pin and GND. The current limit is calculated using the formula: ILIM (A) = 0.5V / RILIM (Ω). Choose a suitable resistor value to set the desired current limit.
The thermal shutdown temperature of the TPS2080DR is typically 150°C. If the device junction temperature exceeds this value, the device will shut down to prevent damage.
