MAX8971
Description
The MAX8971 is a pact, high-frequency, high-efficiency switch-mode charger for a one-cell lithium-ion (Li+) battery. It delivers up to 1.55A of current to the battery from inputs up to 7.5V and withstands transient inputs up to 22V.
Key Features
- include: low-voltage prequalification, charge fault timer, die temperature monitoring, and battery temperature monitoring
- The battery temperature monitoring adjusts the charge current and termination voltage for safe use of secondary lithium-ion batteries
- The IC accepts either a general DC input or USB
- It has programmable automatic input-current limiting to protect upstream charging sources such as USB
- Charge parameters are easily adjustable thro
