Part Information
MAX1501ZETE+ image
RoHS Compliant
The MAX1501 intelligent, constant-current, constant- voltage (CCCV), temperature-regulated battery charger charges a single lithium-ion (Li+) cell or three-cell NiMH/NiCd batteries. The device integrates the current- sense resistor, PMOS pass element, and thermal- regulation circuitry, while eliminating the reverse- blocking Schottky diode to create the simplest charging solution for hand-held equipment. For single-cell Li+ batteries, the MAX1501 functions as a stand-alone charger to control the charging sequence from the prequalification state through fast charge, top- off, and charge termination. With 3-cell NiMH/NiCd batteries, the MAX1501 requires collaboration with a microcontroller to determine the best charging algorithm. Proprietary thermal-regulation circuitry limits the die tem- perature when fast charging or while exposed to high ambient temperatures, allowing maximum charging cur- rent without damaging the charger. The MAX1501 con- tinually supplies a regulated output voltage under no-battery conditions, allowing battery changing without interrupting system power. The device achieves high flexibility by providing an adjustable fast-charge current, top-off current, safety timer (disabled in the MAX1501Z), and thermal-regula- tion setpoint. Other features include input power detec- tion (ACOK) and input under-/overvoltage protection. The MAX1501 provides active-low control inputs. The MAX1501 accepts a 4.5V to 13V supply, but disables charging when the input voltage exceeds 6.5V, preventing excessive power dissipation. The MAX1501 operates over the extended temperature range (-40°C to +85°C) and is available in a compact 16-pin thermally enhanced 5mm x 5mm thin QFN package with 0.8mm profile.
