BATTERY CURRENT SENSING
The MCP6401/1R/1U/2/4/6/7/9 op amps’ Common
Mode Input Range, which goes 0.3V beyond both
supply rails, supports their use in high-side and low-
side battery current sensing applications. The low
quiescent current (45 A, typical) helps prolong battery
life, and the rail-to-rail output supports detection of low
currents.
Figure 4-9 shows a high-side battery current sensor
circuit. The 10
Ω resistor is sized to minimize power
losses. The battery current (IDD) through the 10Ω
resistor causes its top terminal to be more negative
than the bottom terminal. This keeps the Common
Mode input voltage of the op amp below VDD, which is
within its allowed range. The output of the op amp will
also be below VDD, which is within its Maximum Output
Voltage Swing specification.

INSTRUMENTATION AMPLIFIER
The MCP6401/1R/1U/2/4/6/7/9 op amps are well
suited for conditioning sensor signals in battery-
powered applications. Figure 4-10 shows a two op amp
instrumentation amplifier, using the MCP6402, that
works well for applications requiring rejection of
Common Mode noise at higher gains. The reference
voltage (VREF) is supplied by a low impedance source.
In single supply applications, VREF is typically VDD/2.
