● Overtemperature warning and protection (Shutdown)

● High voltage serial interface for communication

● TPQFP package

Description

The Atmel^®ATA6824C 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, Atmel ATA6824C 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 micro-

controller 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. Atmel ATA6824C contains a voltage regulator to supply the microcon-

troller; 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 10%. For communication a high voltage

serial interface with a maximum data range of 20kBaud is integrated.
