AN1156: Battery Fuel Measurement Using Delta-Sigma
ADC Devices
The battery fuel status indicator is a common feature of
the battery-supported handheld devices. The battery fuel
measurement is achieved by measuring the discharging and
charging currents in real time. The discharging current is the
current coming out from the battery and the charging current
is the current flowing into the battery. The fuel used (mAH)
and the fuel remaining (mAH) are calculated by tracking the
discharging and charging currents over time. The fuel used
is the total discharged current over time and the remaining
fuel is simply the subtraction of the fuel used from the fully
charged fuel.
Evaluation Boards
Microchip offers a number of boards to help evaluate device
families. Contact your local Microchip sales office for a
demonstration.
MCP1252DM-BKLT: MCP1252 Charge Pump Backlight
Demonstration Board
The MCP1252 Charge Pump Backlight LED Demo Board
demonstrates the use of a Charge Pump device in an LED
application. The board also serves as a platform to evaluate
the MCP1252 device in general. The MCP1252-ADJ is an
excellent choice for biasing the backlighting or driving other
LED applications. Light intensity is controlled uniformly
through the use of ballast resistors. The peak intensity
is set by the feedback to the MCP1252-ADJ. Dimming is
accomplished by pulse width modulating the shutdown pin of
the device.
The board also features a PIC10F206 microcontroller in a
SOT-23 package, which is used to provide an enable signal
to the MCP1252. The PIC microcontroller also accepts a
push-button input that allows the user to adjust the white
LEDs to five different light intensities, in addition to placing
the system in a standby mode that consumes less than 1 mA
of current (typical).
MCP1252EV: MCP1252/53 Evaluation Kit
The MCP1252/3 Evaluation Board is an evaluation
kit designed to support Microchip’s MCP1252-33X50,
MCP1252-ADJ, MCP1253-33X50 and MCP1253-ADJ
low noise, positive-regulated charge pump devices. The
evaluation kit is fully assembled and tested. The kit is useful
for evaluating simple stand-alone operation or for evaluating
applications interfaced with a microcontroller.

MCP1256/7/8/9EV: MCP1256/7/8/9 Charge Pump
Evaluation Board
The MCP1256/7/8/9 Charge Pump Evaluation Board
is an evaluation and demonstration tool for Microchip’s
MCP1256/7/8/9 Regulated 3.3V, Low-Ripple Charge
Pumps with Low Operating Current Sleep mode or Bypass
mode. The design provides for dynamic versatility. The
MCP1256/7/8/9 Charge Pump Evaluation Board is setup
to evaluate simple, stand-alone, DC-to-DC conversion. Two
evaluation circuits are provided, demonstrating the versatility
of the MCP1256/7/8/9 device family. One evaluation circuit
utilizes the MCP1256, demonstrating the Sleep mode feature
along with a power good indication. The other evaluation
circuit utilizes the MCP1259, demonstrating the unique
Bypass mode feature along with a low battery indication.

MCP1601EV: MCP1601 Buck Regulator Evaluation Board
The MCP1601 Buck Regulator Evaluation Board
demonstrates Microchip’s MCP1601 Synchronous Buck
Regulator, developed for battery powered applications as well
as distributed power applications. The MCP1601 Evaluation
Board is capable of operation over the entire 2.7V to 5.5V
input range of the MCP1601 device. Two 2-position DIP
switches are used, one to select the output voltage (1.8V,
2.05V, 2.45V or 3.28V) and one that turns the MCP1601
on and off with the other position selecting the mode of
operation (PWM-pulse width modulation or PFM-pulse
frequency modulation). Surface mount test points are used
to apply power and load in addition to probing several points
in the test circuit.
MCP1612EV: MCP1612 Synchronous Buck Regulator
Evaluation Board
The MCP1612 Synchronous Buck Regulator Evaluation Board
features Microchip’s 1A 1.4 MHz synchronous buck regulator
in two buck converter applications. The first application uses
the MCP1612 in an 8-lead MSOP package. This converter
has four (0.8V, 1.0V, 1.2V and 1.4V) selectable output
voltages available. The second application features the
MCP1612 in an 8-pin DFN package. This converter also has
four (0.8V, 1.7V, 2.4V and 3.3V) selectable output voltages. A
shutdown terminal is also provided for each converter.
MCP1650EV: MCP1650 Boost Controller Evaluation Board
The MCP1650 Boost Controller Evaluation Board
demonstrates Microchip’s MCP165X Boost Controller product
family in two high-power, boost-converter applications. The
first application features the MCP1651 (8-pin MSOP) with the
low battery detect feature and provides a regulated 5V output
with an input voltage range of 2.8V to 4.8V. The second
application uses the MCP1653 (10-pin MSOP), with both low
battery detect and power good features. The input voltage for
this application is 3.3V, with the output boosted to 12V.
