Maxim MAX1607ESA+

USB 开关1不需要700mA

Overview

The MAX1607ESA is a current-limited 60mΩ switch with built-in fault blanking. Its accurate, preset 0.7A to 1.0A current limit makes it ideal for USB applications. Its low quiescent supply current (14μA) and standby current (1μA) conserve battery power in portable applications. The MAX1607ESA operates with inputs from +2.7V to +5.5V, making it ideal for both 3V and 5V systems. An overcurrent signal (active-low OC) notifies the microprocessor that the internal current limit has been reached. A 10ms overcurrent-blanking feature allows momentary faults (such as those caused when hot-swapping into a capacitive load) to be ignored, thus preventing false alarms to the host system. This blanking also prevents an active-low OC signal from being issued when the device is powering up. The MAX1607ESA has several safety features to ensure that the USB port is protected. Built-in thermal-overload protection limits power dissipation and junction temperature. The device also has accurate internal current-limiting circuitry to protect the input supply against overload. The MAX1607ESA is a pin-compatible upgrade to Texas Instruments' TPS2014, TPS2015, and TPS2041 for USB applications. The same die is available in a space-saving 10-pin μMAX package (MAX1693) and can be used for next-generation designs. The MAX1694 is similar to the MAX1693, but it has a built-in latch that turns off the power switch in case of a long-term short-circuit condition. The MAX1607ESA is also offered in a 10-pin TDFN package (not pin compatible with Texas Instruments TPS2014, TPS2015, and TPS2041 for USB applications).
