Silego introduces the SLG46580, further expanding the GreenPAK (GPAK) family of programmable mixed-signal ICs. This newest GPAK supports power systems in wearable and handheld market segments. It provides voltage monitoring, power sequencing, reset functions and low drop-out regulators (LDOs) that are configurable in settings and interconnects. The device is the second in the series of parts designed to create ‘Flexible Power Islands’ (FPI). The company developed the concept of FPIs to help designers divide their complex power system into some number of local power regions, or islands. Each of these islands includes the power control, power sequencing and power regulation needed to support loads in the immediate vicinity.
The SLG46580 is available in a 2.0 x 3.0 mm, 20-pin encapsulated plastic package. The company offers the GUI-based GPAK designer software, and GPAK development hardware, to help designers implement their unique configuration to customize the functions to match their 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.
