#128828 - Battery mcu noise
Hello
I am using a wireless control with 8051 MCU / cygnal now in this Im using chargeable battries NiMH 1.2V , three in series to power my circuit ,The problem is the Lcd display gets currupted and the MCU is gone after some time of use , I have only 0.1uF capacitor at the powersupply source , and MCU section and RF section totaly shielded and Isolated , I guess this battery is the culprit , Any suggestions regarding the issue ?. Can a rechargable battery damage the mcu ,BTW I am using protection while recharging and switching off the circuitry from charger during charge time .
