SILICON MONOLITHIC
INTEGRATED CIRCUIT
The LIN SBC is a monolithic integrated circuit combining many functions
frequently used by automotive LIN distributed slave nodes. It incorporates:
- Single voltage regulator with low power modes
- LIN physical interface.
- Wake up inputs.
- Triple high side driver
- Current sense op amp
• Vdd: Low drop voltage regulator, current limitation, over temperature
detection, monitoring and reset function, current capability 50mA.
• Programmable window watchdog
• Three operational modes (normal, stop and sleep modes)
• Low current consumption in sleep and stop modes
• LIN physical interface compatible with LIN standard.
• Two external high voltage wake-up inputs
• Dual high side switches, relay driver capability, internal clamp, PWM
capability.
• Single low current high side switch, 50mA capability for switch bias and hall
sensor supply
• Current sense amplifier
• Nominal DC operating voltage from 5.5 to 27V
• 40V maximum transient voltage
• Wake up capabilities (wake up inputs, LIN interface)
