The ATA6824 is designed for DC motor control application in automotive high temperatureenvironment like in mechatronic assemblies in the vicinity of the hot engine, e.g.turbo charger. With a maximum junction temperature of 200°C, ATA6824 is suitablefor applications with an ambient temperature up to 150°C.The IC includes 4 driver stages to control 4 external power MOSFETs. An externalmicrocontroller provides the direction signal and the PWM frequency. In PWM operation,the high-side switches are permanently on while the low-side switches areactivated by the PWM frequency. ATA6824 contains a voltage regulator to supply themicrocontroller; via the input pin VMODE the output voltage can be set to 5V or 3.3Vrespectively.The on-chip window watchdog timer provides a pin-programmable time window. Thewatchdog is internally trimmed to an accuracy of 10% SPI with a maximum data rateof 20 kBaud.
