Overview
The VNI8200XPTR-32, produced by STMicroelectronics, is an octal high-side smart power solid-state relay designed using the VIPower™ technology. This monolithic 8-channel driver is capable of driving any type of load with one side connected to ground. It operates within a voltage range of 10.5 V to 36 V and features a low supply current, making it highly efficient. The device supports both serial (SPI) and parallel control interfaces, providing flexibility in system design.

Q & A
- What is the voltage operating range of the VNI8200XPTR-32?
The VNI8200XPTR-32 operates within a voltage range of 10.5 V to 36 V.
- What is the output current per channel for the VNI8200XPTR-32?
The output current per channel for the VNI8200XPTR-32 is 1.0 A.
- Does the VNI8200XPTR-32 support both SPI and parallel interfaces?
- What is the DC-DC output current capability of the VNI8200XPTR-32?
The DC-DC output current capability is 100 mA.
- What kind of protection features does the VNI8200XPTR-32 have?
The VNI8200XPTR-32 features per-channel overload and short-circuit protection, overtemperature protection, overvoltage protection, and loss of GND protection.
- How does the VNI8200XPTR-32 handle thermal shutdown?
The device has channel-independent thermal shutdown and case temperature protection, which automatically turns off overloaded channels when the junction or case temperature exceeds the protection threshold.
- What is the purpose of the LED matrix in the VNI8200XPTR-32?
The 4x2 LED matrix is used for efficient output state LEDs driving.
- Can the VNI8200XPTR-32 drive inductive loads?
- What are some common applications of the VNI8200XPTR-32?
- How does the watchdog function work in the VNI8200XPTR-32?
The watchdog function is enabled via the WD_EN pin and can be reset by an H-L transition on the WD pin. If the watchdog counter elapses before the reset, the IC enters an internal reset state, disabling all outputs.
