Description
(Input) Filter capacitor input for digital supply voltage.
(Bidirectional) Programmable general purpose digital input/output pin (4) or LED driver.
(Bidirectional) Programmable general purpose digital input/output pin (5) or LED driver.
(Bidirectional) Programmable general purpose digital input/output pin (6) or LED driver.
(Bidirectional) Programmable general purpose digital input/output pin (7) or LED driver.
SMBus clock pin connection.
SMBus data pin connection.
(Input) Cell voltage input for the fourth highest voltage cell in a series string.
(Input) Cell voltage input for the third highest voltage cell in a series string.
(Input) Cell voltage input for the second highest voltage cell in a series string.
(Input) Cell voltage input for the first or highest voltage cell in a series string.
(Input) Analog supply voltage input.
Analog ground reference point.
(Input) Current measurement A/D input from positive side of the current sense resistor.
(Input) Current measurement A/D input from negative side of the current sense resistor.
(Input) A/D input for use with an external temperature circuit. This is the midpoint
connection of a voltage divider, where the upper leg is a thermistor (103ETB type) and the
lower leg is a 3.65 KOhm resistor. This input should not go above 150 mV.
(Output) Reference voltage output for use with temperature measuring A/D circuit. This
150 mV output is the top leg of the voltage divider and connects to an external thermistor.
External bias resistor.
(Bidirectional) Programmable general purpose digital input/output pin (8).
(Bidirectional) Programmable general purpose digital input/output pin (9).
(Bidirectional) Programmable general purpose digital input/output pin (10). Open-drain,
high-voltage tolerant.
(Input) Master Clear. Must be pulled up for normal operation.
(Bidirectional) Programmable general purpose digital input/output pin (12). Open-drain,
high-voltage tolerant.
(Bidirectional) Programmable general purpose digital input/output pin (0) or LED driver.
(Bidirectional) Programmable general purpose digital input/output pin (1) or LED driver.
(Bidirectional) Programmable general purpose digital input/output pin (2) or LED driver.
(Bidirectional) Programmable general purpose digital input/output pin (3) or LED driver.
Digital ground reference point.
