Silego’s latest chip in its GreenPAKTM (GPAK) family of Programmable Mixed-Signal ICs (CMICs) includes voltage monitoring, power sequencing, reset functions and low drop-out regulators (LDOs), that are configurable in settings and interconnect.
It is the second device in the series of parts designed to create “Flexible Power Islands” (FPI).
Using FPIs, designers can divide their power system into some number of local power regions, or islands, each of which includes the power control, power sequencing and power regulation needed to support loads in the immediate vicinity.
Silego believes this technique results in higher performance and a more efficient solution that can be flexibly tailored to the requirements of each individual system.
The new device – the SLG46580 – captures many of these necessary power system functions (power monitoring, sequencing, reset and power switching) in a 2.0 x 3.0 mm 20 pin fully encapsulated plastic package.
Using Silego’s GUI-based GPAK Designe Software, and GPAK development hardware, designers can implement their unique configuration of the device, thereby customizing the functions to match their unique power requirements.
The SLG46580 has four LDOs, each with a maximum output current of 150 mAs. Each of the LDOs has a programmable output voltage level that can be set to one of thirty-two different values from 0.9 V to 4.35 V, and also have programmable options for slew-rate selection and fault detection.
“Power system designers want more flexibility than is offered in PMIC devices, and higher integration than can be achieved using discrete devices. FPIs provide a unique combination of flexibility and integration that addresses the challenges in developing power systems for mobile devices,” says Silego’s Nathan John, “the flexibility provided is very close to a full-custom integrated circuit design, and the very small size allows the design engineer to place them close to critical loads for maximum efficiency. We believe this is yet another example of how Silego’s CMIC strategy provides value to customers.”
