Detailed Description
The MAX1758 includes all of the functions necessary to
charge 1, 2, 3, or 4 Li+ battery cells in series. It
includes a step-down DC-DC converter that controls
charging voltage and current. It also includes input
source current limiting, battery temperature monitoring,
battery undervoltage precharging, battery fault indica-
tion, and a state machine with timers for charge termi-
nation.
The DC-DC converter uses an internal power MOSFET
switch to convert the input voltage to the charging cur-
rent or voltage. Figure 1 shows the typical application
circuit. Figure 2 shows a typical charging sequence and
Figure 3 shows the functional diagram. The charging
current is set by the voltage at ISETOUT. The battery
voltage is measured at the BATT pin. The battery regu-
lation voltage limit is set to 4.2V per cell and can be
adjusted ±5% by changing the voltage at the VADJ pin.
By limiting the adjust range, the voltage limit accuracy is
better than 1% while using 1% setting resistors.
