MAX1645-MAX1645A规格书详情
General Description
The MAX1645 are high-efficiency battery chargers capable of charging batteries of any chemistry type. It uses the Intel System Management Bus (SMBus) to control voltage and current charge outputs.
When charging lithium-ion (Li+) batteries, the MAX1645 automatically transition from regulating current to regulating voltage. The MAX1645 can also limit line input current so as not to exceed a predetermined current drawn from the DC source. A 175s charge safety timer prevents “runaway charging” should the MAX1645 stop receiving charging voltage/ current commands.
The MAX1645 employs a next-generation synchronous buck control circuity that lowers the minimum input-to-output voltage drop by allowing the duty cycle to exceed 99. The MAX1645 can easily charge one to four series Li+ cells.
