描述
The MAX20333/A/B/C/D/E/F/G/H/I/J/K/L/M/N programmable current-limit switches feature internal current limiting to prevent damage to host devices due to faulty load conditions. These current limit switches feature a low 23mΩ (typ) on-resistance and operate from a +3.5V to +22V iinput voltage range (MAX20333/A/B/C/D/E/F/G/H/I/J/K), or +3.3V to +22V input voltage range (MAX20333L/M/N).
The MAX20333 family has three working modes: normal mode (NM), high current mode (HCM), and low power mode (LPM). In NM, the device offers a programmable current-limit protection from 0.2A to 4.75A. The current-limit threshold can be programmed by connecting a suitable resistor to the SETI bump. When the current reaches the programmed threshold, the part prevents the current to further increase. The device can react in three different ways while in current limit: autoretry, latchoff, and continuous. The voltage on the SETI bump is proportional to the current flowing out of the OUT bump at any time and can be read by an ADC.
In high current mode (HCM), the current-limit threshold is multiplied by two, with an internal upper limit set at 5.5A. The voltage on SETI is proportional to the current flowing into IN, but multiplied by a factor 0.5. In low power mode (LPM), the current consumption of the part is dramatically reduced, and the on-resistance is 420mΩ (typ), while still offering an overcurrent protection. The switch is open when the current flowing through the switch exceeds 0.4A (typ).
The devices are available in a 15-bump (2.1mm x 1.52mm) WLP package and operate over the -40°C to +85°C extended temperature range.
