PIN FUNCTION DESCRIPTION
Pin
Function
Description
1
Comparator Inverting
Input
This is the Uncommitted Comparator Inverting input. It is typically connected to a resistor
divider to monitor a voltage.
2
Comparator Noninverting
Input
This is the Uncommitted Comparator Noninverting input. It is typically connected to a
reference voltage.
3
N.C.
No connection. This pin is not internally connected.
4, 5, 12, 13
GND
These pins are the control circuit grounds and are connected to the source and load ground
returns. They are part of the IC lead frame and can be used for heatsinking.
6
Comparator Output
This is the Uncommitted Comparator output. It is an open collector sinkonly output requiring
a pullup resistor.
7
Reset
This is the Reset Comparator output. It is an open collector sinkonly output requiring a
pullup resistor.
8
Power Warning
This is the Power Warning Comparator output. It is an open collector sinkonly output
requiring a pullup resistor.
9
Power Sense
This is the Power Warning Comparator noninverting input. It is typically connected to a
resistor divider to monitor the input power source voltage.
10
Hysteresis Adjust
The Power Warning Comparator hysteresis is programmed by a resistor connected from this
pin to ground.
11
Regulator Output
This is the 5.0 V Regulator output.
14
V
CC
This pin is the positive supply input of the control IC.
15
Chip Disable
This input is used to switch the IC into a standby mode turning off all outputs.
16
V
ref
This is the 2.6 V Reference output. It is intended to be used in conjunction with the Power
Warning and Uncommitted comparators.
OPERATING DESCRIPTION
The MC34160 series is a monolithic voltage regulator and
supervisory circuit containing many of the necessary
monitoring functions required in microprocessor based
systems. It is specifically designed for appliance and
industrial applications, offering the designer a cost effective
solution with minimal external components. These devices
are specified for operation over an input voltage of 7.0 V to
40 V, and with a junction temperature of 40
°
to +150
°
C. A
typical microprocessor application is shown in Figure 11.
Regulator
The 5.0 V regulator is designed to source in excess of
100 mA output current and is short circuit protected. The
output has a guaranteed tolerance of
±
5.0% over line, load,
and temperature. Internal thermal shutdown circuitry is
included to limit the maximum junction temperature to a
safe level. When activated, typically at 170
°
C, the
regulator output turns off.
In specific situations a combination of input and output
bypass capacitors may be required for regulator stability. If
the regulator is located an appreciable distance (
≥
4
″
) from
the supply filter, an input bypass capacitor (C
in
) of 0.33 F
or greater is suggested. Output capacitance values of less
than 5.0 nF may cause regulator instability at light load
(
≤
1.0 mA) and cold temperature. An output bypass
capacitor of 0.1 F or greater is recommended to ensure
stability under all load conditions. The capacitors selected
must provide good high frequency characteristics.
Good construction techniques should be used to
minimize ground loops and lead resistance drops since the
regulator does not have external sense inputs.
Reference
The 2.6 V bandgap reference is short circuit protected
and has a guaranteed output tolerance of
±
5.0% over line,
load, and temperature. It is intended to be used in
conjunction with the Power Warning and Uncommitted
comparator. The reference can source in excess of 2.0 mA
and sink a maximum of 10 A. For additional current
sinking capability, an external load resistor to ground must
be used.
Reference biasing is internally derived from either V
CC
or V
O
, allowing proper operation if either drops below
nominal.
Chip Disable
This input is used to switch the IC into a standby mode.
When activated, internal biasing for the entire die is
removed causing all outputs to turn off. This reduces the
power supply current (I
CC
) to less than 0.3 mA.
