C6D-1109010 is a wide band, DC recessed digital amplifier module produced by Infineon Technologies. It is designed for automotive DC-spike protection in applications such as electronic power steering (EPS) and anti-lock braking systems (ABS). The device includes built-in ESD protection and operates from a wide operating voltage range of 7 to 35 V. It is designed to protect automotive systems from extreme electrical transients such as from load-dump and reverse battery.

In a typical application in a car, the C6D-1109010 is placed across the DC bus of an automotive system or on the positive and negative leads of a component. Signals are coupled from the protected area to the amplifier via the high-frequency filter. The reverse current flow diode prevents induction of negative voltage on the supply side. The common-mode input amplifier is driven from the supply voltage and enables a high attenuation of the DC-spike. The application of the C6D-1109010 reduces the number of components and board space by providing high ESD protection for automotive systems.

The C6D-1109010 amplifier module consists of a large-signal common-mode feedback amplifier and a pair of low-pass filters which reduce the positive and negative transient voltage applied to the inputs. The module has a fixed gain of approximately 1V/V, which is adjustable via a voltage divider. Additionally, the device provides fast output slew rate limiting. This ensures that the output voltage stays within the allowed operating range of the protected component during the transient period. The amplifier is designed to operate with an input voltage range of 7 to 35 V and can handle transients exceeding 400 V.

The common-mode feedback amplifier works as an AC coupled feedback amplifier. It has a load resistor connected from its output to the amplifier’s non-inverting input in order to set the gain. The amplifier also has an input protection diode to provide ESD protection to the inputs. The low-pass filters reduce the amplitudes of the transient signals, allowing the amplifier to operate with lower input voltages.

The C6D-1109010 offers excellent protection against DC-spike transients. In addition, the device also provides ESD protection to the inputs. This helps to protect the protected component from voltage surges and enables the system to operate reliably even in the presence of transients.

The C6D-1109010 is an ideal solution for automotive applications requiring protection from DC-spike transients. The device is compact, cost-effective and offers excellent ESD protection. The device is suitable for use in a wide range of applications, including electronic power steering, anti-lock braking systems, and other automotive power circuits.
