SSL3250A

Photo flash dual LED driver

If the SSL3250A is used in Direct enable mode and external resistors are used, place the

external resistors near the SSL3250A, to minimize disturbance on the output current.

Connect the other end of the resistors to a ‘clean’ ground, that is ground that is not

carrying any large currents. It is preferable to connect all resistor grounds to one trace and

connect that trace to the GND pin of the SSL3250A.

The preferred minimum trace width for the high current width is 15 mil per Ampere.

10. Limiting values

[1]

Tolerant to the specified maximum voltage while operating. Do not apply voltages externally; this may cause

permanent damage to the device.

[2]

Equivalent to discharging a 200 pF capacitor through a 0.75

µH coil and a 10 Ω resistor.

[3]

Equivalent to discharging the device (charged with > 10 M

Ω resistor) through a 1 Ω measurement resistor.

Limiting values

In accordance with the Absolute Maximum Rating System (IEC 60134).Voltages referenced to GND.
