DESCRIPTION
0V to +5V amplitude fan tachometer input. (Default) /
General purpose output.
This multi-functional pin is programmable.
0V to +5V amplitude fan tachometer input. (Default) /
General purpose output.
This multi-functional pin is programmable.
Fan speed control PWM output. This pin is default
open-drain. It can be programmed as an output pin
which can drive a HIGH or a LOW.
Fan speed control PWM output. This pin is default
open-drain. It can be programmed as an output pin
which can drive a HIGH or a LOW.
Active-Low output. This pin will be a logic LOW when
fan1 or fan2 is abnormally stopped. (Default) /
General purpose output.
This multi-functional pin is programmable.
Power down input. When set this pin LOW, all output
pins would be tristate except the pin15 RESET# which
will keep HIGH.
System Management Interrupt.
Over temperature Shutdown Output.
Serial Bus Clock.
Serial Bus bi-directional Data.
Active-Low output. This pin will be a logic LOW when
Battery abnormally drops below the low limit or above
the high limit. (Default) /
General purpose output.
This multi-functional pin is programmable.
Ground.
0V to 4.096V FSR Analog Inputs. (This pin should be
connected to DC BATTERY. If this voltage is above
4.096V, it should be reduced with the external resistors
so that the input voltage will be under 4.096V)
