MAX889SESA Description

Short technical summary and product information.

The MAX889SESA is a high-frequency, regulated, inverting charge pump IC manufactured by Analog Devices (formerly Maxim Integrated). It is designed to deliver a regulated negative output voltage at loads up to 200mA.

This device operates with an input voltage range of +2.7V to +5.5V, producing an adjustable regulated output from -2.5V to -VIN. Key electrical features include a 200mA output current capability, up to 2MHz switching frequency allowing for small capacitors, and a low 0.05Ω output resistance in regulation. It also incorporates soft-start, foldback current limiting, short-circuit, and thermal shutdown protection.

The MAX889SESA includes a logic-controlled shutdown mode that consumes only 0.1µA, making it suitable for battery-powered applications. It is available in an 8-pin SO package, designed for surface mount applications.

Applications for the MAX889SESA include TFT panels, hard disk drives, camcorders, digital cameras, measurement instruments, and other battery-powered devices requiring a regulated negative voltage.
