MAX889SESA+ Description

Short technical summary and product information.

The MAX889SESA+ is a high-frequency, regulated, inverting charge pump IC from Analog Devices, designed to deliver a negative output voltage at loads up to 200mA. It accepts an input voltage range of +2.7V to +5.5V and produces an adjustable regulated output from -2.5V to -VIN.

 

This device features a 1MHz switching frequency, allowing for the use of small capacitors, making it suitable for space-limited applications. Key electrical characteristics include a low 0.05Ω output resistance in regulation, soft-start, and foldback current limiting. It also incorporates short-circuit and thermal shutdown protection for enhanced reliability.

 

The MAX889SESA+ is available in an 8-pin SOIC package, suitable for surface mount applications. It also includes a logic-controlled shutdown mode with a very low 0.1µA quiescent current, making it ideal for battery-powered devices.

 

Applications for this charge pump include TFT panels, hard disk drives, camcorders, digital cameras, measurement instruments, and other battery-powered systems requiring a regulated negative voltage.
