ZDS1009

SM-8 COMPLEMENTARY CURRENT MIRROR

FEATURES

• Excellent Temperature Tracking Characteristics

• Compact Cost Effective Solution

• Simplifies Circuit Implementation

• Broad application base from

Single Cell Li-ion High Side Current sense chargers to

Multi-cell Lead-Acid systems

• Only 4 Connections required

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

applications base including battery charge

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.

Thedevicefunctionsbysensingthevoltagedeveloped

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. This

signal can then be used, for example, to close the

control loop to a controller IC, for a DC-DC converter

providing charge to a battery.
