ADVANCE INFORMATION Ail information in this data sheet is preliminary and subject to change. MAXIMA 4/87 2A, Current-Limited, High-Side P-Channel Switch with Thermal Shutdown General Description The MAX869L. P-channel load switch features an accu- rate user-set current limit and iow on-resistance. This switch is designed to protect your power source from shorts and surges by limiting current and preventing the system supply from being pulled low. The input volt- age range is 2.7V to 5.5V. The MAX&69L features a 2A, 45mQ switch controlled by a logic signal. Current-limit accuracy is +21%, and can be set from 400mA to 2.4A using a single resistor. The device has a iow 12uA quiescent supply current, which reduces to 2uA max in shutdown. It features ther- mal-shutdown protection and a Jogic-signal output pin (FAULT) that signals when there is an overcurrent or overtemperature condition. For other devices in this family, consult the Selector Guide.
