Gumstix has implemented the TPS65950 integrated power management IC from Texas Instruments on each Overo COM. ·
The·TPS65950 integrated power management IC has 3 DC/DC's, 11 LDO's, audio codec, USB HS transceiver & charger.
The power management features are still in an experimental branch of Linux-OMAP, so Gumstix hasn't completed any testing. The current plan is to wait until these power management features are merged into the mainline Linux-OMAP to alleviate any concerns for their stability.
A Gumstix Overo COM draws·250 mA @ 4v (with Wifi & Bluetooth switched off)
For the TPS65950 interrupt lines on the Overo COM,
- Gumstix Overo COM FAB revisions >= 2516, INT1 is connected to GPIO_0_4030 IRD on the OMAP.
- Gumstix Overo COM FAB revisions <= 2410, INT1 is connected toGPIO112_4030 IRQ on the OMAP.
