VN920 Single channel high-side solid-state relay Features Type RDS(on) IOUT VCC VN920 VN920-B5 VN920SO 16 m 30 A 36 V P2PAK PENTAWATT CMOS compatible input Proportional load current sense Shorted load protection Under-voltage and over-voltage shutdown Description Over-voltage clamp Thermal shutdown Current limitation Protection against loss of ground and loss of VCC Very low standby power dissipation Reverse battery protected (see Application schematic ) The VN920 is a monolithic device designed in STMicroelectronics VIPower M0-3 technology. The VN920 is intended for driving any type of load with one side connected to ground. The active VCC pin voltage clamp protects the device against low energy spikes (see ISO7637 transient compatibility table). Active current limitation combined with thermal shutdown and automatic restart protects the device against over-load. SO-16L The device integrates an analog current sense output which delivers a current proportional to the load current. The device automatically turns off in the case where the ground pin becomes disconnected. Table 1.

Application schematic +5V VCC Rprot INPUT Dld C Rprot OUTPUT CURRENT SENSE RSENSE GND VGND RGND DGND 3.1 GND protection network against reverse battery 3.1.1 Solution 1: resistor in the ground line (RGND only) This can be used with any type of load. The following is an indication on how to dimension the RGND resistor. 1. RGND 600mV / (IS(on)max). 2. RGND (- VCC) / (- IGND) where - IGND is the DC reverse ground pin current and can be found in the absolute maximum rating section of the device datasheet. Power Dissipation in RGND (when VCC < 0: during reverse battery situations) is: PD= (- VCC)2/ RGND This resistor can be shared amongst several different HSDs. Please note that the value of this resistor should be calculated with formula (1) where IS(on)max becomes the sum of the maximum on-state currents of the different devices. Please note that if the microprocessor ground is not shared by the device ground then the RGND will produce a shift (IS(on)max * RGND) in the input thresholds and the status output values. This shift will vary depending on how many devices are ON in the case of several high-side drivers sharing the same RGND. If the calculated power dissipation leads to a large resistor or several devices have to share the same resistor then ST suggests to utilize Solution 2 (see below). 16/34 VN920 3.1.2 Application information Solution 2: diode (DGND) in the ground line A resistor (RGND = 1k) should be inserted in parallel to DGND if the device drives an inductive load. This small signal diode can be safely shared amongst several different HSDs. Also in this case, the presence of the ground network will produce a shift ( 600mV) in the input threshold and in the status output values if the microprocessor ground is not common to the device ground. This shift will not vary if more than one HSD shares the same diode/resistor network. Series resistor in INPUT and STATUS lines are also required to prevent that, during battery voltage transient, the current exceeds the absolute maximum rating. Safest configuration for unused INPUT and STATUS pin is to leave them unconnected. 3.2 Load dump protection Dld is necessary (Voltage Transient Suppressor) if the load dump peak voltage exceeds the VCC max DC rating. The same applies if the device is subject to transients on the VCC line that are greater than the ones shown in the ISO 7637-2: 2004(E) table. 3.3 MCU I/Os protection If a ground protection network is used and negative transient are present on the VCC line, the control pins will be pulled negative. ST suggests to insert a resistor (Rprot) in line to prevent the C I/Os pins to latch-up. The value of these resistors is a compromise between the leakage current of C and the current required by the HSD I/Os (Input levels compatibility) with the latch-up limit of C I/Os. -VCCpeak/Ilatchup Rprot (VOHC-VIH-VGND) / IIHmax Calculation example: For VCCpeak= - 100V and Ilatchup 20mA; VOHC 4.5V 5k Rprot 65k. Recommended values: Rprot =10k . 17/34 Application information 3.4 VN920 P2PAK maximum demagnetization energy (VCC = 13.5V) Figure 20.
