| • PWM and Direction-controlled Driving of Four Externally-powered NMOS Transistors • High Temperature Capability up to 200°C Junction • A Programmable Dead Time Is Included to Avoid Peak Currents Within the H-bridge • Integrated Charge Pump to Provide Gate Voltages for High-side Drivers and to Supply The ATA6824 is designed for DC motor control application in automotive high temperature environment 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 suitable for applications with an ambient temperature up to 150°C. The IC includes 4 driver stages to control 4 external power MOSFETs. An external microcontroller provides the direction signal and the PWM frequency. In PWM operation, the high-side switches are permanently on while the low-side switches are activated by the PWM frequency. ATA6824 contains a voltage regulator to supply the microcontroller via the input pin VMODE the output voltage can be set to 5V or 3.3V respectively. The on-chip window watchdog timer provides a pin-programmable time window. The watchdog is internally trimmed to an accuracy of For communication a high voltage serial interface with a maximum data range of 20 kBaud is integrated.
