What are the key features of MAX14745KEWX+T?
- 5-channel integrated PMIC consolidates battery charging and power management into a single 36-ball WLCSP, minimizing wearable PCB area
- Adjustable threshold control allows flexible battery charge voltage and current settings for different Li-Ion cell capacities
- Wafer-level chip-scale package (WLCSP, 6×6 ball grid, R-PBGA-B36) enables ultra-compact designs for smartwatches and fitness bands
What is MAX14745KEWX+T used for?
The MAX14745KEWX+T is optimized for smartwatches, fitness bands, and hearables where every cubic millimeter of PCB space must be conserved. Its 5-channel architecture supplies the display, processor, radio, and sensor subsystems from a single Li-Ion cell with integrated charge management. Medical wearables and continuous health monitors also benefit from its adjustable charge thresholds and compact WLCSP footprint.

Frequently Asked Questions
How does the MAX14745KEWX+T's 5-channel PMIC architecture reduce BOM complexity in a smartwatch design?
By integrating 5 regulated output channels plus battery charger management in a single 36-ball WLCSP, the MAX14745KEWX+T replaces 5 or more discrete LDOs and a separate charger IC. This consolidation reduces the component count from roughly 15–20 passives and ICs to a single chip with a few decoupling capacitors, saving over 30 mm² of PCB area and significantly cutting assembly cost in high-volume wearable production.
What is the WLCSP package size of the MAX14745KEWX+T, and why is this critical for wrist-worn device PCBs?
The MAX14745KEWX+T uses a 36-ball WLCSP with a 6×6 ball array, giving a die-level package footprint of approximately 2.5 mm × 2.5 mm at 0.4 mm ball pitch. Wrist-worn devices typically have PCB areas under 200 mm², so replacing multiple discrete PMICs with this single chip frees significant board space for a larger battery or additional sensors, directly improving device endurance and feature density.
How does the adjustable threshold feature of the MAX14745KEWX+T benefit designs that use different battery cell capacities?
The adjustable charge threshold allows the same MAX14745KEWX+T design to accommodate Li-Ion cells from 50 mAh to 500 mAh by scaling charge current and termination voltage through external resistors or register programming. A 50 mAh cell requires C/10 termination at roughly 5 mA, while a 500 mAh cell needs up to 50 mA — the flexible threshold prevents overcharge damage and maximizes capacity utilization across the product family without a hardware respin.
