Datasheet Details

Part number	MAX1894
Manufacturer	Maxim
File Size	308.40 KB
Description	Advanced Li+ Battery-Pack Protectors
Datasheet	MAX1894_MaximIntegratedProducts.pdf

The MAX1894/MAX1924 are lithium-ion/lithium-polymer (Li+) battery-pack protector ICs for 3- or 4-series Li+ battery packs.

All protection thresholds and delays do not require any external components and are trimmed at the factory. If any cell voltage drops below the undervoltage threshold, the MAX1894/MAX1924 disconnect the pack from the load and power down to prevent deep discharge of the pack. The MAX1894/MAX1924 offer a trickle-charge feature, which provides a low-current path to safely charge a deeply discharged pack. The MAX1894/ MAX1924 also have two logic-level inputs, which can be used by a microcontroller.
