The MAX1501 is an intelligent, constant-current, constant-voltage (CCCV), temperature-regulated battery charger that charges a single lithium-ion (Li+) cell or three-cell NiMH/NiCd batteries. This Maxim device integrates the current-sense resistor, PMOS pass element, and thermal-regulation circuitry, while eliminating the reverse-blocking Schottky diode to create a simple charging solution for handheld equipment. It functions as a standalone charger to control the charging sequence from the prequalification state through fast charge, top-off, and charge termination for single-cell Li+ or three-cell NiMH/NiCd batteries.
Alternatively, the MAX1501 collaborates with a host microprocessor to determine the best charging algorithm. Proprietary thermal regulation circuitry limits the die temperature when fast charging or while exposed to high ambient temperatures. The device achieves high flexibility by providing an adjustable fast-charge current, top-off current, safety timer, and thermal-regulation setpoint. Other features include input power detection (ACOK) and input under-/overvoltage protection.
The MAX1501 accepts a 4,5 to 13 V supply, but disables charging when the input voltage exceeds 6,5 V, preventing excessive power dissipation. It comes in 16-pin 5 x 5 mm thin QFN package with 0,8 mm profile.
