Automotive Dashboard Indicator Driver Reference Design

This TI reference design is an automotive dashboard signaling solution that contains a monolithic, medium voltage, low current power 12-bit shift register designed specifically for use in systems requiring relatively moderate load power, such as LEDs in car dashboards. This design is part of a complete automotive dashboard system solution optimized for the mid-range dashboard market. The entire solution supports 4.5-40V system functionality and can withstand cold crank, start-stop and load dump conditions.

characteristic

• ● Wide input voltage range: 4.5V - 40V, can withstand start/stop, cold start and load dump conditions
• ● The small and accurate Rdson of the internal MOSFET enables lower heat dissipation through the LED and more accurate output current
• ● Slow switching speed: rise time = 207ns, fall time = 128ns, which obviously helps reduce EMI
• ● Thermal shutdown protection helps avoid overheating and damage to the TLC6C5912-Q1
