The ATA6026 is used to drive a continuous-current motor in a full H-bridge configura-
tion. An external microcontroller controls the driving function of the ATA6026 by
providing a PWM signal and a direction signal, and allows the usage of the ATA6026
in a windshield wiper application, for example.
Description
The ATA6026 supports PWM and direction-controlled driving of four external power
MOSFETs with two external bootstrap capacitors. The PWM control is performed by
the high-side switch. The opposite low-side switch is permanently ON in the driving
phase. Motor braking is performed using the low-side switches. A programmable dead
time is included to prevent peak currents within the H-bridge. The maximum PWM fre-
quency is 30 kHz.
