single-supply bridge circuit
inductive kickback
RAIL-TO-RAIL OUTPUT
Free-Running Square Wave Amplifier
Programmable High Resolution Window Comparator
1.the circuit floats up from the single-supply (12 V to 30 V) return.
2.Current is monitored in the power supply return where a 0.1 Ω shunt resistor, RSENSE, creates a very small voltage drop.
3.he voltage drop across R2 increases with IL increasing, so VOUT decreases with higher supply current being sensed.

4.When in single-supply applications, driving motors or actuators in two directions is often accomplished using an H bridge.
