The SA52128B is an eight half-bridge motor driver solution for automotive, industrial, and other mechatronic applications. The half-bridges are fully controllable, facilitating forward, reverse, coasting, and braking motor operations. All the functions are programmable via 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 pin can be used to notify the system in the event of a fault. The device is available in a TSSOP24E package with an exposed pad to enhance thermal dissipation.
