AN8353UB
High Efficiency Car Dashboard Dimmer IC
s Overview
The AN8353UB is a dimmer IC to control illumination of the
car dashboard at high efficiency and high performance by pulse
width control. It outputs pulses at a duty proprotional to an
input voltage.
s Features
• Low power consumption by pulse control
• External ON/OFF control by the standby pin
• Pulse frequency range : 50Hz to 10kHz
• Built-in overvoltage protective circuit approx. 20V
• Wide operating ambient temperature range : –40˚C to+100˚C
• All products temperature cycle, high reliability by normal
and high temperature checks reliability equivalent to the air
bags requested in U.S.
