MAX17006 Evaluation Kit
The MAX17006 is an evaluation kit for the MAX17006
that utilizes two single-package MOSFETs for the
MAX17006 internal synchronous step-down converter.
The MAX17006 EV kit is a complete and fully assem-
bled and tested surface-mount PCB that demonstrates
the MAX17006 highly integrated, multichemistry battery
charger controller. The MAX17006 integrates a high-
efficiency, synchronous-rectified step-down DC-DC
converter to implement a precision constant-current
and constant-voltage charger. The MAX17006 thermally
optimized high-frequency architecture adjusts the EV
kit’s typical switching frequency to 1.2MHz to control
the power dissipation in the high-side MOSFET, reduc-
ing output capacitance and inductance.
The MAX17006 EV kit utilizes two single-package
n-channel MOSFETs for high-side and low-side switching
for the MAX17006 synchronous converter, and two
n-channel MOSFETs and one p-channel MOSFET for
main power-source selection. The EV kit is designed to
operate from a single DC power supply that provides
10V to 25V and 5A of current.
The MAX17006 EV kit circuit is capable of supplying
power to a load connected to the SYS_LOAD output,
while simultaneously charging the battery pack con-
nected between BATT+ and BATT-. During normal
operation, the EV kit circuit selects the ADAPTER or
the BATT+ input, through MOSFET Q1, as the main
power source for the load connected at SYS_LOAD.
Once the main AC adapter is selected as the power
source, the EV kit circuit monitors the input current
through the IINP connector. The input current is
defined as the combined system-load current and
battery-charge current when the ADAPTER input is
the main power source. When the input current
exceeds the EV kit input-current-limit threshold, the
battery-charge current is reduced to give priority to
the system load.
The EV kit’s input-current-limit threshold is configured
to 4A with resistor R1. The EV kit’s cell count and
maximum battery-charge-current thresholds are pro-
grammable with user-adjusted analog signals. The EV
kit features on-board circuitry that allows the user to
adjust or set the voltage thresholds at each of these
inputs. Jumper JU1 selects the MAX17006 EV kit for
