The DRV81008-Q1 is an eight channel low-side driver with integrated protection and diagnostic features. The Device is specially designed to control relays in automotive and industrial applications.
A serial peripheral interface (SPI) with daisy chain capability is utilized for control and diagnosis of the loads as well as of the device. Two input pins with mapping functionality are available for direct PWM control of the outputs. The device supports Limp Home mode for fail-safe activation.
Each low-side switch of the DRV81008-Q1 has 630mΩ ON resistance. The device can support 330mA current per output when all the eight channels are ON simultaneously. Integrated clamp circuits on each output dissipates the stored energy during turning OFF inductive loads.
The DRV81008-Q1 supports various protection features such as undervoltage, overvoltage, short circuit and open load detection. High level of integration with embedded protection and diagnostic features make the DRV81008-Q1 an excellent choice for automotive body and powertrain applications.
