MAX1772EEI+T 产品详情

The MAX1772EEI is a highly-integrated, multichemistry battery-charger control IC that simplifies the construction of accurate and efficient chargers. The MAX1772EEI uses analog inputs to control charge current and voltage and can be programmed by the host or hardwired. High efficiency is achieved by a buck topology with synchronous rectification. Maximum current drawn from the AC adapter is programmable to avoid overloading the AC adapter when supplying the load and the battery charger simultaneously. This enables the user to reduce the cost of the AC adapter. The MAX1772EEI provides outputs that can be used to monitor the current drawn from the AC adapter, battery-charging current, and the presence of an AC adapter. The MAX1772EEI can charge two to four lithium-ion (Li+) series cells, easily providing 4A. When charging, the MAX1772EEI automatically transitions from regulating current to regulating voltage. It is available in a space-saving 28-pin QSOP package.
