MAX1985ETP+T belongs to power management integrated circuit (PMIC) and is a type of LED driver IC (integrated circuit). It is capable of driving up to four LEDs connected in series and can operate with a single input voltage. The IC provides the option of over-voltage and over current protection, to ensure a reliable operation of the lighting system. The device has short circuit protection, over-temperature protection and over-voltage protection which gives it the ability to safely control the LED system.

The device has two operating mode which is low power mode (LP) and high power mode (HP). In the LP mode, the output current can be varied from 0 to 1.3A and the output voltage is limited to 4.6V. In the HP mode, the output current is limited to 1.3A and the output voltage can be varied from 5V up to 12.6V.The device also supports constant current or constant voltage operation and allows the user to select the operating mode via a control pin. With the help of these two modes, the device can be used for different applications.

The MAX1985ETP+T is a versatile LED driver IC that is capable of driving both single or multiple LEDs in series. It supports wide range of input voltages and the output current can be varied from zero to maximum. With the advanced protection features, the device can be used in applications where the LED load is exposed to unpredictable and extreme environment.
