Typical value with all loads connected ■ ■ ■ Main – Inrush current active management by power limitation – Very low stand-by current – 3.0V CMOS compatible input – Optimized electromagnetic emission – Very low electromagnetic susceptibility – In compliance with the 2002/95/ec european directive Diagnostic Functions – Proportional load current sense – High current sense precision for wide range currents – Current sense disable – Thermal shutdown indication – Very low current sense leakage Protections – Undervoltage shut-down – Overvoltage clamp – Load current limitation – Self limiting of fast thermal transients – Protection against loss of ground and loss of VCC – Thermal shut down – Reverse battery protection (see Application schematic) – Electrostatic discharge protection February 2008 PowerSSO-12 PowerSSO-24 Application ■ All types of resistive, inductive and capacitive loads ■ Suitable as LED driver Description The VND5050AJ-E, VND5050AK-E is a monolithic device made using STMicroelectronics VIPower M0-5 technology. It is intended for driving resistive or inductive loads with one side connected to ground. Active VCC pin voltage clamp protects the device against low energy spikes (see ISO7637 transient compatibility table). This device integrates an analog current sense which delivers a current proportional to the load current (according to a known ratio) when CS_DIS is driven low or left open. When CS_DIS is driven high, the current sense pin is in a high impedance condition. Output current limitation protects the device in overload condition. In case of long overload duration, the device limits the dissipated power to safe level up to thermal shut-down intervention. Thermal shut-down with automatic restart allows the device to recover normal operation as soon as fault condition disappears.

Application schematic +5V VCC Rprot CS_DIS Dld µC Rprot INPUT OUTPUT Rprot CURRENT SENSE GND RSENSE CEXT VGND RGND DGND Note: Channel 2 has the same internal circuit as channel 1. 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. 21/38 Application information VND5050AJ-E / VND5050AK-E 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). 3.1.2 Solution 2 : diode (DGND) in the ground line 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 (≈ 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. 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 µC I/Os pins to latch-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. 22/38 VND5050AJ-E / VND5050AK-E 3.4 Application information Maximum demagnetization energy (VCC = 13.5V) Figure 27.
