NCV7755DQR2G

NCV7755DQR2G is an automotive-grade integrated driver with eight high side switches. The device provides drive capability of up to 700mA per channel and is protected from overload and over temperature conditions. All the channels have integrated output clamps for switching inductive loads, and multiple start pulses for bulbs, and can be mapped to two internal PWM generators for LED loads. The output control and diagnostic reporting is via SPI. Additionally, INx pins can be mapped to any of the outputs for direct control. A dedicated limp−home mode enables operational control of two high−side drivers via logic input pins. Application includes automotive body control unit, automotive engine control unit, relay drive, bulb drive and LED drive.

• 8 high−side channels, for relays (flyback clamps), bulbs (multiple pulse in−rush scheme)
• LEDs (internal PWM generator), 2.3A peak current (max)
• Paralleling of two output pair is allowed
• SPI control (16bit), frame error detection (16bits + 8n bits)
• Daisy chain capable, two input pins with mapping for PWM operation
• Low quiescent current in sleep mode, limp home mode with auto−retry
• Supports cranking voltage of 3V Minimum on VS
• Reverse polarity protection, loss of ground protection, power−on reset (VDD)
• Operating junction temperature range from -40 to 150°C
• SSOP24−EP package
