Abstract : A novel type of leakage current protector chip ,implemented in the mixed signal 0 6μm CMOS process ,is
presented. This chip has the advantages of low power dissipation (10mW) ,accurate protection control based o2n digit
al response delay time and integration of multi functions such as leakage current/ overΖ voltage/ over load detection
and protection ,auto switch on and so forth. Additionally ,the chip is programmable to suit different three level pro
tection applications with a high anti interference ability.
Key words : leakage current protector ; IC design ; programmable IC
