The VN5E050AJ-E is designed to drive 12V automotive grounded loads delivering protection, diagnostics and easy 3V and 5V CMOS compatible interface with any microcontroller. The device integrates advanced protective functions such as load current limitation, inrush and overload active management by power limitation, over-temperature shut-off with auto-restart and over-voltage active clamp. A dedicated analog current sense pin is associated with every output channel in order to provide Ehnanced diagnostic functions including fast detection of overload and short-circuit to ground through power limitation indication, overtemperature indication, short-circuit to Vcc diagnosis and ON & OFF state open load detection. The current sensing and diagnostic feedback of the whole device can be disabled by pulling the CS_DIS pin high to allow sharing of the external sense resistor with other similar devices.

Application schematic +5V VCC Rprot CS_DIS Dld ΜCU Rprot IINPUT OUTPUT Rprot CURRENT SENSE GND RGND RSENSE Cext 3.1 VGND DGND GND protection network against reverse battery This section provides two solutions for implementing a ground 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 show 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 24/37 VN5E050AJ-E Application information 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 requires the use of a large resistor, or several devices have to share the same resistor, then ST suggests using solution 2 below. 3.1.2 Solution 2: diode (DGND) in the ground line Note that a resistor (RGND=1kΩ) 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 (j600mV) 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. 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/O protection If a ground protection network is used and negative transients 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 µC I/O pins from latching up. The value of these resistors is a compromise between the leakage current of µC and the current required by the HSD I/Os (Input levels compatibility) with the latch-up limit of µC I/Os: -VCCpeak/Ilatchup ≤ Rprot ≤ (VOHμC-VIH-VGND) / IIHmax Calculation example: For VCCpeak = - 100V and Ilatchup ≥ 20mA; VOHµC ≥ 4.5V 5kΩ ≤ Rprot ≤ 180kΩ Recommended values: Rprot =10kΩ, CEXT=10nF. 25/37 Application information 3.4 VN5E050AJ-E Current sense and diagnostic The current sense pin performs a double function (see Figure 33: Current sense and diagnostic): ● Current mirror of the load current in normal operation, delivering a current proportional to the load one according to a know ratio KX. The current ISENSE can be easily converted to a voltage VSENSE by means of an external resistor RSENSE. Linearity between IOUT and VSENSE is ensured up to 5V minimum (see parameter VSENSE in Table 9: Current sense (8V<VCC<18V)). The current sense accuracy depends on the output current (refer to current sense electrical characteristics Table 9: Current sense (8V<VCC<18V)). ● Diagnostic flag in fault conditions, delivering a fixed voltage VSENSEH up to a maximum current ISENSEH in case of the following fault conditions (refer to Truth table): – Power limitation activation – Over-temperature – Short to VCC in OFF state – Open load in OFF state with additional external components. A logic level high on CS_DIS pin sets at the same time all the current sense pins of the device in a high impedance state, thus disabling the current monitoring and diagnostic detection. This feature allows multiplexing of the microcontroller analog inputs by sharing of sense resistance and ADC line among different devices. Figure 33.

Small or no current is delivered by the current sense during the on state depending on the nature of the short circuit. OFF state open load with external circuitry Detection of an open load in off mode requires an external pull-up resistor RPU connecting the output to a positive supply voltage VPU. It is preferable VPU to be switched off during the module stand-by mode in order to avoid the overall stand-by current consumption to increase in normal conditions, i.e. when load is connected. An external pull down resistor RPD connected between output and GND is mandatory to avoid misdetection in case of floating outputs in off state (see Figure 33: Current sense and diagnostic). RPD must be selected in order to ensure VOUT < VOLmin unless pulled up by the external circuitry: VOUT Pull − up _ OFF = RPD ⋅ I L ( off 2) f < VOL min = 2V RPD ≤ 22 KΩ is recommended. For proper open load detection in off state, the external pull-up resistor must be selected according to the following formula: VOUT Pull − up _ ON = RPD ⋅ VPU − RPU ⋅ RPD ⋅ I L ( off 2) r RPU + RPD > VOL max = 4V For the values of VOLmin ,VOLmax, IL(off2)r and IL(off2)f see Table 10: Open load detection (8V<VCC<18V). 27/37 Application information 3.5 VN5E050AJ-E Maximum demagnetization energy (VCC = 13.5V) Figure 34.
