Capacitor area is another contributor to ESR.

Capacitors that are physically large will have a lower

ESR when compared to an equivalent material

smaller capacitor. These larger devices can improve

circuit transient response when compared to an

equal value capacitor in a smaller package size.

Thermal Protection

The AAT3143 has a built-in thermal protection cir-

cuit that will shut down the charge pump if the die

temperature rises above the thermal limit, as is the

case during a short-circuit of the CP pin.
