[1] Total current = IBAT + IBAT(CP).
[2] Standby currents valid provided VBAT and VCC(MOD) > 9 V.
[3] Total current = ICC(MOD) + ICC(DIGC).
[4] Does not include current through pins INTN or WDTON pull-up resistors.
[5] All channels ON; with FET Crss = 210 pF; fSPI = 3 MHz.
[6] Monitored on pin VBAT(CP).
