ZDS1009 SM-8 COMPLEMENTARY CURRENT MIRROR DESCRIPTION The ZDS1009 current mirror has been developed specifically for high side, current sense plus level translation applications and as such will find a broad a p p li c ati ons bas e i nc l udi ng ba t t e ry ch a rg e management, DC motor control and over current monitoring functions. It is of particular interest for current sense applications for feedback purposes in fast battery chargers for Li-Ion cell based systems. The device functions by sensing the voltage developed across an external (user defined) high side current sense resistor, and by an arrangement of current mirrors refer this sensed voltage, with or without multiplication, to a low side referenced signal.
