Power Management ICs for Intel Atom E600

Before we discuss our fourth topic, let us first do some recap. On our first discussion, we discussed about Microchip's MCU with dual peripheral. It is a low-cost designed MCU that features a dual ADC peripheral. Second, we discussed about Intersil's highly integrated li-ion battery charger. It is a complete battery charger designed for single cell Li-ion and Li-polymer batteries. Then we discussed about ROHM's wearable key device. It is a breakthrough key-shaped sensor synergy from ROHM and Kionix with LAPIS Semiconductors Bluetooth® LE communication IC and sensor hub microcontroller. And now, we will be discussing, still from ROHM, the power management ICs.

 
CPU, memory modules, evaluation and development boards, IOH, and clock IC are examples of main system blocks. ROHM power management ICs supplies power to the main system blocks. ROHM's BD9591AMWV and BD9594AMWV are designed specifically for Intel® Atom™ E600 series processors. A complicated supply sequence controller is also built in, eliminating the need for a special power supply control IC while enabling configuration of an optimized system power supply and environment for the said processor. 

Features

• Complicated power supply sequence (which conventionally was performed via microcontroller) is built in, reducing user design load.
• System-optimized efficient power supply design requires only a single FET for greater compactness.
• Used in conjunction with an BU7335MWV CGIC provides additional platform support.

Tiny over current protector

Before this post, we talked about a low-ohmic current sensing device which was for portable gadgets. Now, we will be talking about a current sensing IC which protects heavy equipments, power tools, and induction heaters. Introducing Mouser's IR25750L Current Sensing IC.

On what applications can IR25750L be used? What are the features of this IC? Well, here are the features and application of IR25750L.

The more power a system needs, the greater chance of over current to occur. So when we use our power tools, heavy equipments, and even our induction heaters, make sure there's an IR25750L Current Sensing IC in it. Better safe than sorry right! Ciao!
