Motor Driver ICs for High-temperature Applications
ATA6824, ATA6827, ATA6832
Atmel®’s driver ICs are also available for high-temperature applications. In mechatronic solutions, for
example, turbo charger or exhaust gas recirculation systems, many flaps have to be controlled by DC
motor driver ICs which are located very close to the hot engine. Due to the advantages of Atmel’s own SOI
technology SMARTIS™, these driver ICs can withstand ambient temperatures of up to 150°C/302°F.
ATA6827
The ATA6827 is a fully protected triple half-bridge driver IC that controls 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 of driving currents up to 1.0A. The drivers are internally connected to form 3 half-bridges and
can be controlled separately via a standard serial data interface.
ATA6832
The power stages of the ATA6832 are also combined to 3 half-bridges. Due to the enhanced PWM signal of up to
25 kHz, the ATA6832 is able to generate a smooth control of a DC motor, for example, without any noise.

ATA6824
If higher output currents are required, the MꢀSFET driver IC ATA6824 is recommended. This device
includes in addition a 5V/3V voltage regulator for microcontroller supply, a window watchdog and a serial inter-
face. The integrated motor control unit avoids peak currents within the H-bridge.
