• Supply Voltage up to 40 V • RDSon Typically at 25°C, Maximum at 150°C • Up to A Output Current • Three Half-bridge Outputs Formed by Three High-side and Three Low-side Drivers • Capable to Switch all Kinds of Loads Such as DC Motors, Bulbs, Resistors, Capacitors and Inductors • No Shoot-through Current • Very Low Quiescent Current IS < 5 µA in Standby Mode versus Total Temperature Range • Outputs Short-circuit Protected • Overtemperature Protection for Each Switch and Overtemperature Prewarning • Undervoltage Protection • Various Diagnostic Functions Such as 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 Triple Halfbridge DMOS Output Driver with Serial Input Control The T6818/ATA6828 are fully protected driver interfaces designed in 0.8-µm BCDMOS technology. They are used to control up to 3 different loads by a microcontroller in automotive and industrial applications. Each of the 3 high-side and 3 low-side drivers is capable to drive currents up to A. The drivers are internally connected to form 3 half-bridges and can be controlled separately from a standard serial data interface. Therefore, all kinds of loads such as bulbs, resistors, capacitors and inductors can be combined. The IC design especially supports the application of H-bridges to drive DC motors. Protection is guaranteed regarding short-circuit conditions, overtemperature and undervoltage. Various diagnostic functions and a very low quiescent current in stand-by-mode opens a wide range of applications. Automotive qualification protection against conducted interferences, EMC protection and 2-kV ESD protection gives added value and enhanced quality for exacting requirements of automotive applications.
