MAXIM INTEGRATED / ANALOG DEVICES MAX20094ATIBVY Backup Battery Charger
The MAX20094ATIBVY is an automotive-qualified backup battery charger and boost controller designed for critical systems in vehicles. It combines a configurable constant-current/constant-voltage (CC/CV) battery charger with a high-efficiency synchronous boost controller, capable of supply critical systems during primary power loss. It features diagnostic capabilities like battery health checks, configurable thresholds, and a compact 28-pin side-wettable TQFN package, operating over -40°C to +125°C and tolerant of load dump conditions. Ideal for automotive telematics, single and multicell battery backup systems, it supports voltages from 3 to 36V and charges batteries up to 1A efficiently.
