The MAX20094/MAX20095 ICs combine a configurable constant-current/constant-voltage (CC/CV) battery charger with a high-efficiency synchronous boost controller to supply critical systems in the event the primary power source is lost. In addition, diagnostic features are available to check battery state-of-health (SOH) and IC functionality. Charging thresholds and the boost output voltage are configurable to support popular battery chemistries and a wide range of cell counts. To support system integration, the ICs have an I2C target port through which configuration and status bits can be accessed.

Switching frequency of 2.2MHz also helps to reduce system cost by minimizing inductor size. The ICs also include a precision battery SOH check and have built-in functionality to minimize leakage current out of the backup battery (BUB).

The MAX20094/MAX20095 are available in a 28-pin (5mm x 5mm) side-wettable TQFN package and are AECQ-100 qualified.

Applications

  • Automotive Telematics Battery Backup

Product Detail

The MAX20094/MAX20095 evaluation kits (EV kits) are fully assembled and tested application circuits for the MAX20094/MAX20095 backup battery chargers and boost controllers with I2C capability. The EV kits are set up to provide the user with a convenient method to assess the constant-current/constant-voltage (CC/CV) battery charger, state-of-health (SOH) diagnostic features, and the boost controller.

Both EV kits are recommended for use with the free MAX20094 companion GUI and an I2C interface board, such as the Maxim Integrated command module (MINIQUSB). The MINIQUSB enables I2C communication through the USB port of a PC by emulating a 2-wire interface. The EV system includes both the EV kit and the MINIQUSB command module. Note: The EV kit can also be used as a stand-alone board without these items. The EV kit can also evaluate the pin-compatible MAX20095 with IC replacement of U1.

Applications

  • Automotive Telematics Battery Backup
  • Single or Multicell Battery-Backup Systems
