EVAL-LTM4719-AZ

EVAL-LTM4719-AZ is an evaluation board featuring the LTM®4719, a 42V dual input, 150mA synchronous buck power μModule® (micromodule) regulator with an integrated battery health monitor and a low-dropout linear regulator. The EVAL-LTM4719-AZ has a wide operating input range of 2.4V to 42V and supports seamless transition between the two separate input power sources. The output has a range of 1V to 4.2V and can source up to 150mA of continuous output current. It also features an EXTVCC jumper (JP3) to VBUS for improved efficiency in some applications. The system can be monitored through active low (VALID1, VALID2, PRIORITY), and PG indicators. There are accurate VSET1 and VSET2 comparators to program independent undervoltage lockout (UVLO) thresholds. Fault protection features include input UVLO, power good, current limit, and overtemperature protection. The built-in precision coulomb counter supports input voltages from 1.8V to 5.5V and a peak current of up to 100mA.

• Compatible w/ LTpowerPlay: easy use GUI for coulomb counter, access Coulomb counter register data
• Optional supercapacitor balancer
• EVAL-LTM4719-AZ can be connected directly to PC at P1 using DC1613A I2C/SMBus/ PMBus dongle
• LTpowerPlay® allows the user to run a GUI and configure a battery SoH monitor
