DC Input Sources
The MAX8600/MAX8601 operating input voltage range
is 4.15V to 7V. The device survives input voltages up to
16V without damage to the IC. If the input voltage is
greater than 7.5V (typ), the IC stops charging. An
appropriate power supply must provide at least 4.2V
plus the voltage drop across the internal pass transistor
when sourcing the desired maximum charging current.
VIN(MIN) > 4.2V + ICHARGE(MAX) x RON
where RON is the input-to-BAT resistance (typically
0.5
Ω). Failure to meet this requirement results in an
incomplete charge or increased charge time.
Stand-Alone Li+ Charger
The MAX8600 provides a complete Li+ charging solu-
tion. Figure 3 shows the MAX8600 as a stand-alone Li+
battery charger. The 2k
Ω resistor connected to SETI
sets a charging current of 750mA. The LED indicates
when fast-charge has begun. When fast-charge is com-
plete, the LED turns off.
USB-Powered Li+ Charger (MAX8601)
The universal serial bus (USB) provides a high-speed
serial communication port as well as power for the
MAX8600/MAX8601
Single-/Dual-Input 1-Cell Li+ Chargers with
OVP Protection and Programmable Charge Timer
