The DRV81004-Q1 is a four-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 used for control and diagnosis of the loads and 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 DRV81004-Q1 has 700mΩ ON resistance. The device can support 470mA current per output when all four channels are ON simultaneously. Integrated clamp circuits on each output dissipates the stored energy when turning OFF inductive loads.
The DRV81004-Q1 supports various protection features such as undervoltage, overvoltage, short circuit, and open load detection. A high level of integration with embedded protection and diagnostic features makes the DRV81004-Q1 an excellent choice for automotive body and powertrain applications, as well as industrial relay control applications.
