MAX4836ETT33C+T is a voltage regulator in the realm of Power Management ICs (PMICs), and more specifically, linear voltage regulators. It is a dual voltage regulator, providing both a low-side and high-side output, and can deliver up to 3A of current. Some notable features of the device include: a wide operating power range, short-circuit protection, adjustable current limit, thermal overload protection, fast overvoltage protection, and some parts are to lead-free.

This specific part is useful in a variety of application fields. It can be used as a battery charger with a wide operating power range, due to its adjustable current limit. The MAX4836ETT33C+T is also capable of controlling the secondary side of a power supply, as it can deliver up to 3A of current and has an overvoltage protection function. Additionally, the device can be used in medical power supplies, as it is designed for short-circuit and thermal overload protection. Lastly, it is also suitable for automotive and industrial applications, because some of the parts are lead-free and designed to meet tight manufacturing tolerances.

The MAX4836ETT33C+T contains two operational amplifier circuits, each with a single digital control pin. By utilizing these pins, the user can set the want output voltage limit. On each side, the ramping circuit is used to set the reference voltage which is compared with a set voltage. If the reference voltage is greater than the set voltage, the power transistor will open and the output voltage will start to rise, and if the reference voltage is lower than the set voltage, the power transistor will close and the output voltage will be decreased. The voltage at the output terminals will be determined by the reference voltage dependence and the voltage limit set with the digital control pins. Additionally, the amplifiers are configured with the enable pin, allowing the user to enable or disable the circuit.

Furthermore, the MAX4836ETT33C+T has short-circuit protection. This protects both the circuit, and the device itself, from damage due to an accidental short-circuit. It also has a thermal overload protection, which will open the circuit at a set temperature, and a fast overvoltage protection, which will block the power transistor from closing if the output voltage exceeds a set level. Both of these protections work towards the goal of a reliable, consistent and durable device.

In conclusion, the MAX4836ETT33C+T is an incredibly versatile dual voltage regulator, with impressive features and an impressive operating power range. It can be used in various application fields and can provide fast overvoltage, short-circuit and thermal overload protection functions. The working principle of the device lies in the two operational amplifier circuits and the digital control pins, allowing user to set the desired output voltage quickly and easily. It is no wonder that the MAX4836ETT33C+T is such a popular voltage regulator in today’s market.
