DESCRIPTION

· The T6818/ATA6828 are fully protected driver interfaces designed in 0.8-µm BCD-MOS technology.
· They control up to 3 different loads via a microcontroller, suitable for automotive and industrial applications.
· Each of the 3 high-side and 3 low-side drivers can drive currents up to 1.5 A.
· The drivers form 3 half-bridges, controlled separately through a standard serial data interface.
· Supports H-bridge applications for DC motor driving.
· Features comprehensive protection against short-circuit, overtemperature, and undervoltage.
· Includes diagnostic functions and low quiescent current in standby mode.
· Automotive qualified with protection against conducted interferences, EMC, and 2-kV ESD.

FEATURES

· Supply voltage up to 40 V.
· RDSon typically 0.5 Ω at 25°C, maximum 1.1 Ω at 150°C.
· Up to 1.5 A output current.
· Three half-bridge outputs formed by three high-side and three low-side drivers.
· Capable of switching various loads including DC motors, bulbs, resistors, capacitors, and inductors.
· No shoot-through current.
· Very low quiescent current IS < 5 µA in standby mode across the total temperature range.
· Outputs are short-circuit protected.
· Overtemperature protection for each switch with overtemperature prewarning.
· Undervoltage protection.
· Diagnostic functions include shorted output, open-load, overtemperature, and power-supply fail detection.
· Serial data interface, daisy chain capable, up to 2 MHz clock frequency.
· SO14 power package.

APPLICATIONS

· Automotive and industrial control systems.
· DC motor driving using H-bridge configurations.
· Switching and controlling various loads like bulbs, resistors, capacitors, and inductors.
