IVDD = 0 to 100µA
IVDD = 100µA to 1mA
VBATA or VBATB= 5V to 19V, VEXTLD = 5V
VBATA = VBATB = 5V, VEXTLD = 5V to 28V
VBATA, VBATB, or VEXTLD = 5V to 19V,
sawtooth at 10V/µs, other supplies = 12V
Hysteresis is typically 50mV
(Note 2)
VTHM_ = 5.5V
VTHMA = VTHMB = 0 to 5.5V
VTHMA = VTHMB = 0 to 5.5V,
VBATA = VBATB = VEXTLD = 4.75V
VTCOMP = 5.5V
THM_ falling with respect to TCOMP
(Note 3)
VACDET = 3V, VACDET < VBATA and VBATB
VACDET = 3V, VACDET < VBATB, VBATA = 0
VACDET = 28V, VACDET > VBATA and VBATB
VACDET falling with respect to VBATA
VACDET falling with respect to VBATB
VBATA = VBATB= 5 x VMINV
VMINV = 0.93V to 2.6V
VBAT_ falling
Typical hysteresis is 100mV
VMINV = 0.93V
VMINV = 2.6V
VBATSEL = 5.5V
