The MAX4821EUP-T is an IC component designed specifically for precision current-limiting applications. It offers an array of key features that make it ideal for various industrial and automotive applications.
This IC utilizes two high-side switches, enabling accurate current-limiting functions. It operates with a supply voltage in the range of 6V to 36V and can withstand transients up to 40V. The power-on reset feature ensures that the outputs are held off until the supply voltage reaches a safe level.
One of the notable features of the MAX4821EUP-T is its programmable current-limiting capability. It allows users to set the current limit to values ranging from 0.3A to 2.5A through an external resistor. The current limit can be adjusted on-the-fly, providing flexibility in various current-limiting scenarios.
The IC has built-in thermal protection, which prevents temperature-related damage to the device. It monitors the junction temperature and reduces the current limit if the temperature exceeds a predetermined threshold. This protection feature ensures the safe operation and longevity of the IC.
Additionally, the MAX4821EUP-T incorporates a short-circuit protection mechanism. It limits the output current to a safe level in case of a short circuit, preventing damage to the IC. This feature safeguards the surrounding components and the overall system.
The IC is designed to operate in harsh environments, with a temperature range of -40°C to +125°C
