Logic Compatible Enable
Inputs
The NCV47411 is a dual integrated low dropout regulator with
100 mA per channel designed for use in harsh automotive
environments. It includes wide operating temperature and input
voltage ranges. The device is offered with adjustable voltage version
available in 3% output voltage accuracy. It has a high peak input
voltage tolerance and reverse input voltage protection. It also provides
overcurrent protection, overtemperature protection and enable for
control of the state of the output voltage of each channel. The
integrated current sense feature provides diagnosis and system
protection functionality. The current limit of the device is adjustable
by resistor connected to CSO pin for each channel. CSO pin output
current creates voltage drop across CSO resistor which is proportional
to output current of each channel.
Features
• Two Adjustable Outputs: (from 3.3 V to 20 V) ±3% Output Voltage
• Enable Inputs (3.3 V Logic Compatible Thresholds)
• Adjustable Current Limit up to 150 mA
• Protection Features:
♦ Current Limitation
♦ Thermal Shutdown
♦ Reverse Input Voltage
• This is a Pb−Free Device
Typical Applications
• Audio and Infotainment System
• Instrument Cluster
• Navigation
• Satellite Radio
