EVAL-LTM4719-AZ

製品概要

The EVAL-LTM4719-AZ evaluation board features 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.

The EVAL-LTM4719-AZ also features an EXTV_CC jumper (JP3) to V_BUS for improved efficiency in some applications. The system can be monitored through VALID1, VALID2, PRIORITY, and PG indicators. There are accurate V_SET1 and V_SET2 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. The EVAL-LTM4719-AZ utilizes jumpers to easily program the peak current limit of the coulomb counter from 5mA to 100mA by setting IPK0 (JP4), IPK1 (JP5), and IPK2 (JP6).

The EVAL-LTM4719-AZ can be connected directly to a PC at P1 using the DC1613A, Analog Devices I²C/SMBus/ PMBus dongle. The LTpowerPlay^® allows the user to run a graphical user interface (GUI) and configure a battery state of health (SoH) monitor.
