PCA9553D/02,112 is the newest product in the PMIC - LED Drivers family. The device is a dual channel MOSFET driver with two channels. The device is designed to drive one high side and one low side N-Channel MOSFET per channel at up to 16A and has a 0.5A gate drive current limit.

The main feature of the PCA9553D/02,112 is the high current switching capability coupled with low RDS(ON) output MOSFETs. The device has a total peak power of 128W, making it suitable for applications requiring high power. It has a wide operating temperature range of -40 to 85degC and is RoHS compliant.

The PCA9553D/02,112 offers an attractive mix of features and performance making it a great option for LED drivers. The device is capable of driving up to 16A of LED current, and its low ON resistance of 0.085Ω per channel allows for very power efficient LED driving. Additionally, the device is able to switch up to six LED channels and support pulse width modulation up to 100Khz per channel. It also offers a number of protection functions including over-voltage, over-current, and reverse current protection.

In terms of its working principle, the PCA9553D/02,112 operates by providing two sets of logic inputs. The logic inputs are used to control the power MOSFETs which drive the LEDs. When the logic low is applied to the control inputs, the corresponding power MOSFETs are opened and the LEDs are turned off. When the logic high is applied to the control inputs, the corresponding power MOSFETs are closed and the LEDs are turned on.

The PCA9553D/02,112 can be used in a wide range of applications such as automotive, industrial, medical, and general purpose LED applications. It could be used to drive white LED backlights or LED displays in automotive headlight assemblies or operating panels, or for LED illumination in industrial applications. It could also be used for LED lighting or signage applications in commercial and residential buildings. In medical applications, it could be used for LED emergency lighting systems.

The PCA9553D/02,112 provides a cost effective solution for driving high current LED loads in low voltage applications. Its integrated MOSFETs, wide operating temperature range, and protection features make it an excellent choice for high performance LED driving applications. Its high power output, wide input voltage range and pulse width modulation capabilities make it an ideal solution for driving multiple LED channels.
