JP4 - VOC_SAMP
VOC_SAMP = 80% configures the IC to regulate VIN to
JP4 = 80% (NOTE: Do not install if JP1 shunt is installed)
80% of OCV. VOC_SAMP = 50% configures the IC to
regulate VIN to 50% of OCV.
JP5 - VREF_SAMP to
VREF_SAMP = GND
Uninstalled (NOTE: Providing an additional leakage path for the VREF_SAMP capacitor for example,
GND
through a 10 M
Ω
scope probe attached to VREF_SAMP, will degrade input voltage regulation
performance).
JP6 - VBAT_OK to
BAT_OK=VOUT_EN configures the buck converter to be
Uninstalled (NOTE: Do not install if JP3 shunt is installed)
VOUT_EN
enabled only when VSTOR is greater than the VBAT_OK
threshold per the resistors (2.786V on the EVM)
