NAME
FUNCTION
LBO/
LBO
Low-Battery Output. LBO/LBO is asserted when BATT drops
below VLTH (MAX6427/MAX6428/MAX6429) or when LTHIN
(MAX6433/MAX6434/MAX6435) drops below VLTHIN, and
remains asserted for at least 140ms after BATT exceeds VHTH
(MAX6427/MAX6428/MAX6429) or VHTHIN (MAX6433/
MAX6434/MAX6435).
BATT
GND
LBOH/
LBOH
Battery-Voltage Input. Input for battery-voltage threshold
monitors and device power supply for factory-trimmed
threshold versions.
Ground
Low-Battery Output High. LBOH/LBOH is asserted when BATT
drops below VHTH- (MAX6430/MAX6431/MAX6432) or when
HTHIN drops below VHTHIN- (MAX6436/MAX6437/ MAX6438). It
remains asserted for at least 140ms after BATT exceeds VHTH+
(MAX6430/MAX6431/MAX6432) or HTHIN rises above VHTHIN+
(MAX6436/MAX6437/MAX6438).
LBOL/
LBOL
HTHIN
LTHIN
VDD
Low-Battery Output Low. LBOL/LBOL is asserted when BATT
drops below VLTH- (MAX6430/MAX6431/MAX6432) or when
LTHIN drops below VLTHIN- (MAX6436/MAX6437/
MAX6438). It remains asserted for at least 140ms after BATT
exceeds VLTH+ (MAX6430/MAX6431/MAX6432) or LTHIN rises
above VLTHIN+ (MAX6436/MAX6437/MAX6438).
HTH Threshold Monitor Input. A resistor-divider network sets
the high threshold associated with LBOH/LBOH.
LTH Threshold Monitor Input. A resistor-divider network sets
the low threshold associated with LBOL/LBOL.
VDD Supply Voltage Input. Device power supply for adjustable
threshold versions.
