Analog Devices EVAL-LTM4719-AZ User Manual

General Description
The EVAL-LTM4719-AZ evaluation board features the
®
LTM 4719, a 42V dual input, 150mA synchronous buck
power µModule ® (micromodule)
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
(JP3) to V for improved efficiency in some
BUS
applications. The system can be monitored through
VALID1, VALID2, PRIORITY, and PG indicators. There
are accurate V and V
SET1
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).
