The LTC
®
1041 is a monolithic CMOS BANG-BANG
controller manufactured using Linear Technology’s
enhanced LTCMOS™ silicon gate process. BANG-BANG
loops are characterized by turning the control element
fully ON or fully OFF to regulate the average value of
the parameter to be controlled. The SET POINT input
determines the average control value and the DELTA input
sets the deadband. The deadband is always 2 x DELTA and
is centered around the SET POINT. Independent control
of the SET POINT and deadband, with no interaction, is
made possible by the unique sampling input structure of
the LTC1041.
An external RC connected to the OSC pin sets the sampling
rate. At the start of each sample, internal power to the
analog section is switched on for
80µs. During this time,
the analog inputs are sampled and compared. After the
comparison is complete, power is switched off. This
achieves extremely low average power consumption
at low sampling rates. CMOS logic holds the output
continuously while consuming virtually no power.
To keep system power at an absolute minimum, a switched
power output (V
P-P
) is provided. External loads, such as
bridge networks and resistive dividers, can be driven by
this switched output.
The output logic sense (i.e., ON = V
+
) can be reversed
(i.e., ON = GND) by interchanging the V
IN
and SET POINT
inputs. This has no other effect on the operation of
the LTC1041.
