PRODUCTION DATA.
The DRV2511-Q1 device features a complete set of protection circuits carefully designed to protect the device against permanent failures due to shorts, over-temperature, over-voltage, and under-voltage scenarios. The INTZ pin signals if an error is detected.
FAULT | TRIGGERING CONDITION
(typical value) |
INTZ | ACTION | LATCH? |
---|---|---|---|---|
Over Current | Output short or short to PVDD or GND | pulled low | Output high impedance | Latched |
Over Temperature | Tj > 150°C | pulled low | Output high impedance | Latched |
Under Voltage | PVDD < 4.5V | – | Output high impedance | Self-clearing |
Over Voltage | PVDD > 27V | – | Output high impedance | Self-clearing |
When the "Latched" conditions happen, the device must be reset with the EN signal in order to clear the fault. If automatic recovery from these conditions is desired, connect the INTZ pin directly to the EN pin. This allows the INTZ pin function to automatically drive the EN pin low which clears the latched condition.
