LS MOSFETs. You can also see the use of wide

copper areas for all of the high current paths.

The low-side sense resistor is composed of three

resistors in parallel (R25, R26, and R27), and is

connected to the input supply and LS MOSFET

source terminals by wide copper areas.

Note the location of the charge pump and supply

bypass capacitors, very close to the IC. The

grounded side of these capacitors is connected

to a ground plane, which is connected to the

device ground pin and exposed pad. The high-

current ground path between the input supply,

input bulk capacitor C19, and MOSFETs is kept

away from this area.
