MAX14752EUE+T

Application Field:

MAX14752EUE+T is an 8-channel, bidirectional, high-voltage, non-latching, analog switch and multiplexer/demultiplexer integrated circuit. It is designed to provide an efficient solution to switching and multiplexing signals in high-voltage power systems.

The device contains simultaneous logic inputs with levels that are translated to either a normally-on (switch open) or normally-off (switch closed) state. It offers wide operating temperature range, up to +85°C, allowing operation in high temperature environments. The MAX14752EUE+T is suited for applications in automotive and industrial products, such as motor controllers, AC/DC converters and UPS systems.

Working Principle:

The MAX14752EUE+T is a comprehensive analog switch and multiplexer/demultiplexer device consisting of 8 channels. Each channel consists of two high-voltage, non-latching, bidirectional switches with common control inputs. The functional blocks also allow for the connection of two common enable/disable controls for each channel.

The switches are controlled by four logic inputs (A, B, C, D). A logic high level at the respective input causes the switch to switch on and vice versa. The switches can be synchronized by two enable/disable inputs (EN1 and EN2). Both enable/disable inputs can be used to simultaneously control the switch on and off state. The switch is opened when at least one of the enable/disable inputs is low and both enable/disable inputs are high, which results in the switch closing.

The MAX14752EUE+T integrated circuit also contains a high-level of ESD protection, allowing for reliable operator control and reducing the need for additional shielding or transient voltage protection components. The device utilizes low RDS(on) and negligible Miller capacitive charge injection, resulting in superior signal fidelity with low distortion and low noise.

The MAX14752EUE+T is also equipped with overcurrent protection, making it suitable for applications in high-power systems to protect against excessive current. The device is designed to withstand up to 100V voltage transients, thus allowing it to switch high-voltage signals without the need for external voltage clamps or transient voltage suppressors.

In summary, the MAX14752EUE+T is an excellent choice for high-performance analog switch and multiplexer/demultiplexer circuits, due to its reliable high-voltage performance, wide operating temperature range, low power consumption and reduced circuit complexity.
