| The Simple Bridge is capable of bi-directional control
of one brushed DC motor or other two-terminal DC load (such as a lamp or
thermoelectric module). The small footprint, low cost, and ease of use allow
the Simple Bridge to fit many design needs. Control of the on-board H-bridge
is accomplished with 4 i/o lines, each controlling a switch of the H-bridge
(2 high-side, and 2 low-side). Using a microcontroller, and pulse width
modulating the low-side switches allows for speed control. Individual control
of the H-bridge switches also allows for dynamic braking. The Simple Bridge
H-bridge is rated for 25A peak, but due to the small package and thermal
issues 6A is about the highest continuous current it will pass before on-board
thermal protection causes it to cut-out. The high peak and moderate continuous
current rating meets the needs of many motor control applications where
large start-up currents are common.
The low-side switches are low rdson MOSFETS (14milliohm) and are controlled
by a MOSFET driver IC for more efficient turn-on/off times when pulse width
modulated. The high-side switches are smart MOSFETs (26milliohm) with over-current,
over-temperature, and under voltage protection built in.
The Simple Bridge is 1.7" wide x 1.6" long x 0.6" tall.
