DESCRIPTION

· The MAX13256 is an H-bridge transformer driver designed for isolated power supplies up to 10W.
· It operates from an 8V to 36V DC supply and drives a transformer’s primary coil with up to 300mA.
· The output voltage is determined by the transformer’s secondary-to-primary winding ratio.
· Features adjustable current limiting, fault detection, and a low-power mode reducing supply current to 0.65mA.
· Available in a compact 10-pin TDFN package, suitable for automotive applications from -40ºC to +125ºC.

FEATURES

· Wide supply range of 8V to 36V with up to 90% efficiency.
· Provides up to 10W to the transformer with undervoltage lockout.
· Compatible with 2.5V to 5V logic interfaces and supports internal or external clock sources.
· Adjustable overcurrent threshold and integrated system protection including fault detection.
· Compact 10-pin TDFN package (3mm x 3mm) saves board space.

APPLICATIONS

· Power meters and isolated fieldbus interfaces.
· 24V PLC supply isolation and medical equipment.
· Motor controls and other applications requiring isolated power supplies.
