The SA52122 is a twelve half-bridge motor driver solution designed for automotive, industrial, and mechatronic applications. The half-bridges are fully controllable, facilitating forward, reverse, coasting, and braking motor operations. All the functions can be programmed through a serial peripheral interface (SPI).
The device includes protection features such as overcurrent protection, open load detection, undervoltage lockout, overvoltage lockout, and thermal shutdown for reliable operation.
The open-drain nFAULT output can be configured to signal fault conditions to the host.
The device is available in a TSSOP24E package with an exposed pad for improved thermal dissipation.
