Digital Potentiometer Solutions
Low Power Applications
Many applications are power sensitive. This is because they
are battery powered or design goals on the power supply.
Microchip Technology’s digital potentiometer families are
low power, with the maximum I
devices. This current is when the serial interface is inactive
and a non-volatile memory write cycle is not active. This
current does not include any current through the resistor
network (the A, B and W pins).

MCP4024, MCP41010, MCP41050, MCP41100, MCP42010,
MCP42050 and MCP42100. Currently all other devices have
a max I
A capability is given in many of the devices to shut down
the resistor network, that is disconnect the resistor network
from the circuit. This can substantially reduce the current
of the system. This shut down mode may be achieved by a
hardware pin (SHDN) or via software through the Terminal
Control register(s). The software shutdown allows devices to
retain this capability while being packaged in the smallest
package since the SHDN pin is not present.
The hardware shutdown forces the resistor network into a
defined condition where the resistor network is disconnected
from the Terminal A pin and the Wiper value is forced to 00h
(Wiper connected to Terminal B). The Wiper register retains
it value so that when shutdown is exited the wiper returns to
it’s previous position.
Devices with Low Power Operation
1. Resistor options are: -202 (2.1 kΩ), -502 (5.0 kΩ), -103 (10.0 kΩ), and -503 (50.0 kΩ).
2. Resistor options are: -502 (5.0 kΩ), -103 (10.0 kΩ), 503 (50.0 kΩ), and -104 (100.0 kΩ).
3. Zero-scale allows the wiper to “directly” connect to Terminal B, while full-scale allows the wiper to “directly” connect to Terminal A.
4. There is one R
5. This current is with the serial interface inactive, and not during an EEPROM write cycle (for non-volatile devices).
6. The serial interface has been tested to 1.8V, the device’s analog characteristics (resistor) have been tested from 2.7V to 5.5V. Review the device’s characterization graphs for information on analog performance between
7. One of the terminal pins (A or B) is internally connected to ground, due to the limitation of the number of pins on the package.
8. Shutdown support via software (TCON register(s)). If device has SHDN pin, software shutdown also fuctions.
9. High voltage command support is for compatibility with the corresponding non-volatile version of the device.

Normal vs. Shutdown Mode
The software shutdown allows control to each of the resistor
network terminal pins. Each resistor network has 4-bit in
a TCON register. A bit for each terminal pin (A, B and W)
and one bit that mimics the hardware shutdown state (the
resistor network is disconnected from the Terminal A pin and
the Wiper value is forced to 00h). This allows the application
to completely control the currents through the digital
potentiometers resistor network(s).
The software shutdown is more flexible then the hardware
shutdown pin, and is available on devices where due
to package selection a hardware shutdown pin was not
implemented.
