The device integrates six total half-bridge high-side and low-side FETs, supporting bidirectional drive for up to five motors; two 1.5-Ω half-bridges, two 300-Ω half-bridges, and two 100-Ω half-bridges. All of these drivers can be controlled with SPI register, PWM signal that can be sourced from the PWM1 pin or IPROPI/PWM2 pin. Each driver also has configurable current regulation feature called ITRIP. Half-bridge protection circuits include overcurrent protection, off-state and active open-load diagnostics.
The diagrams below show common configurations for the integrated half-bridges to support up to five mirror and lock motors, and all mirror motors:
The diagram below shows a configuration for mirror only loads:
