MAX1501
Highly Integrated, Linear Battery Charger with
Thermal Regulation for Portable Applications
14
Maxim Integrated
Figure 7 shows the MAX1501 as a stand-alone trickle or
timer-based NiMH/NiCd battery charger. Connecting
SELV to GND sets the charge termination voltage to 4.5V.
Figure 8 shows the MAX1501 as a P-based
NiMH/NiCd battery charger. Connecting SELV to VL
sets the charge regulation voltage at 4.95V. Connect a
100k
Ω pullup resistor from ACOK to the logic supply
voltage of the P. The logic supply voltage must be
less than 5.5V.
Figure 9 shows the MAX1501 as a P-based single Li+ or
3-cell NiMH/NiCd charger. The states of MODE and
CHGEN set the operating mode of the MAX1501 (Table 1).
Connect a 100k
Ω pullup resistor from ACOK to the logic
supply voltage of the P. The logic supply voltage must be
less than 5.5V.
Figure 10 shows the MAX1501 as an accurate current-
limited low-dropout linear regulator with input overvolt-
age protection (no-battery mode). The output voltage
regulates to 4V, regardless of the state of SELV.
Connect MODE to VL to enable the linear regulator.
Connect MODE to GND to put the device into shut-
down. RSETI sets the maximum output current.
