BCL603C

BCL603C is a highly integrated and ultra-low power consumption Chiplet dedicated charging front-end protection chip for smart rings. It adopts a 4mm wide LGA package form. The smart ring can be designed with a two-layer board FPC, reducing the BOM number by 85% and ensuring a yield of over 95% when bending the PCBA. The specific product features are as follows:

• It integrates 27 devices such as load switches, NTC, TVS, overvoltage protection chips, MOSFET resistors and capacitors

• Operating voltage: 3.6V to 5.5V

• Adjustment of input voltage direction (non-polar input)

• The TVS protection voltage is 5.6V and the clamping voltage is 9.8V

• Overvoltage protection: 6V, output short circuit and overcurrent protection

• ESD: Air discharge ±15kV, contact discharge: 8kV

• Low-power and high-speed load switch

• Low-level reset circuit upon power-on (200ms)

• Temperature monitoring NTC

• Operating temperature range: -40℃ to 80℃
