Maxim Integrated on 14th October’2019 officially released for mass production MAX20333 product – Adjustable Current-Limit Switch with Low Power Mode.
MAX20333 programmable current-limit switch featuring internal current limiting to prevent damage to host devices due to faulty load conditions. It has low 23mΩ (typ) on-resistance and operate from a +3.5V to +22V input voltage range. Device has three working modes: normal mode (NM), high current mode (HCM), and low power mode (LPM).
In NMI mode MAX20333 offers programmable current-limit protection from 0.2A to 4.75A, while in HCM mode current-limit threshold is multiplied by 2, but internally limited by 5.5A. LPM mode offers dramatically reduced power consumption, with on-resistance of 420mΩ (typ), while still offering overcurrent protection (switch opens when current exceeds 0.4A typ.)
MAX20333 can react in three different ways while in current limit: autoretry, latchoff, and continuous, depending on part option, defined by OPN (Ordering Part Number).
These features make MAX20333 ideally suitable to protect devices using USB Type-C power delivery that becomes the market standard for portable and mobile applications.
