4 Series LED Bypass Switches
SPF5047
Data Sheet
Description
The SPF5047 is a bypass switch for the high-
brightness matrix LEDs used in applications such as
automotive headlights. The product includes four series
switches to bypass individual LEDs, whose dimming
systems are externally controlled by a CPU. Each LED
has open and short detections that can send fault flags to
the CPU. Even if one of the four LEDs becomes open,
the open-LED is bypassed by its built-in power
MOSFET so that other LEDs can continue to work
normally. The SPF5047 is supplied in a compact,
surface-mount type HSOP package, with an exposed pad
for enhanced thermal dissipation.
Features
● 4 Searis LED Bypass Switches
● Drives Up to 16 LEDs in Series (with 4 ICs; at VF of
an LED is approx. 3 V)
● Low Noise:
No charge-current-induced noise occrus as each gate
driver uses a negative power souce which requires no
charge-pump circuit.
● High Efficiency:
Optimized trade-offs between switching loss and
switching noise allow highly-accurate control in tr
and tf.
● Fault Flag Reporting
● LED Open Detection
● LED Short Detection
