VN9E30F 6-Channel High-Side Driver

The VN9E30F is a device made using STMicroelectronics VIPower technology. It is intended for driving resistive or inductive loads directly connected to ground. The device is protected against voltage transient on the V_CC pin (see ISO7637 transient compatibility table). Programming, control, and diagnostics are implemented via the SPI bus. A digital current sense feedback for each channel is provided through an integrated 10-bit ADC with 0.1% of FSR. Dedicated trimming bits allow users to adjust the ADC reference current. The device is equipped with six outputs controllable via SPI or with the 2-OTP assignable direct inputs. The device detects open-load in OFF-state conditions.

Real-time diagnostics are available through the SPI bus (open-load, output short to V_CC, overtemperature, communication error, power limitation, or latch-off). Output current limitation protects the device in an overload condition. The device can limit the dissipated power to a safe level up to thermal shutdown intervention. Thermal shutdown can be configured as latched-off or programmable time-limited auto-restart. The device enters a limp home mode in case of loss of digital supply (V_DD), reset of digital memory, or watchdog monitoring time-out event. In limp home mode, each output is set according to the programmed register to be always OFF or according to the 2x direct input pins.
