Hello Everyone,

I'm designing a portable device. Below is the schematic for the power management part.

http://www.4shared.com/photo/5WFqrMHr/screenshot_power_mngmt_Altium.html

List of components:

AC Adaptor - 5V to the circuit

Battery - http://www.farnell.com/datasheets/810103.pdf http://uk.farnell.com/gp-batteries/nta2710/battery-li-ion-3-7v-4400mah-1s1p/dp/1848660

BQ24314 - Overvoltage and Overcurrent protection for the Li-Ion charger

BQ24032A - Li-Ion Charger (can charger from USB and/or AC Adaptor)

BQ27510-G1 - Fuel Gauge

MIC5209 - LDO Voltage regulator at 3.3V

MAX660 - Voltage Inverter

TPS72301 - Negative Voltager regulator at -3.3V

Please note: whenever you find red labels, these are net labels and they are connected by the bottom left corner of the text.

Some of the Net Labels go the MicroProcessor PIC18LF4550 which is not shown in this screenshot.

Please give me any comments/suggestions/feedback on my design.

I can't read the schematic because the resolution is too low. However, if you have read the IC's datasheets and designed your components properly, I would expect your design to work properly. You can always expect to have some redesign based on your initial testing.

Hello Michael,

Thanks for your reply. I believe the image should be very clear , have you tried downloading the image and expanding it ? or have you judged upon the preview? Please use this link instead http://db.tt/UZKzgaET

I have indeed designed upon the datasheets, however, I'm not sure about my overall topology. I can't afford the time and cost of redesigning so if you could please point out any major errors, I would be very grateful.

Thanks

I know it doesn't look very clear, but any comments will be appreciated.
