Atmel ATA6826C Triple Half-bridge DMOS Output Driver with Serial Input Control DATASHEET Features Supply voltage up to 40V R typically 0.8 at 25C, Maximum 1.5 at 150C DSon Up to 1.0A output current Three half-bridge outputs formed by three high-side and three low-side drivers Capable of switching all kinds of loads such as DC motors, bulbs, resistors, capacitors and inductors No shoot-through current Very low quiescent current I < 2A in Standby Mode versus total temperature S 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 2MHz clock frequency SO14 power package 9213DAUTO09/121. Description The Atmel ATA6826C is a fully protected Triple Half-bridge designed in Smart Power SOI Technology, used to control up to three different loads by a microcontroller in automotive and industrial applications. Each of the three high-side and three low-side drivers is capable of driving currents up to 1.0A. The drivers are internally connected to form three 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 standby mode opens a wide range of applications. Automotive qualification gives added value and enhanced quality for exacting requirements of automotive applications. Figure 1-1.
