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). The device detects open load condition both in on and off state, when STAT_DIS is left open or driven low. Output shorted to VCC is detected in the off state. When STAT_DIS is driven high, STATUS pin is in high impedance state. 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.. Diagnostic Functions ■ ■ Open drain status output On state open load detection ■ Off state open load detection ■ Thermal shutdown indication Protections ■ Undervoltage shut-down ■ Overvoltage clamp ■ Output stuck to VCC detection ■ Load current limitation Order codes Package PowerSSO-12 PowerSSO-24 Part number (Tube) VND5050J-E VND5050K-E Part number (Tape & Reel) VND5050J-E13TR VND5050K-E13TR March 2006 Rev 1 1/28 www.st.com 28 Contents VND5050J-E / VND5050K-E Contents 1 2 Block diagram and pin description . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 Electrical specifications . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4 2.1 2.2 2.3 2.4 Absolute Maximum Ratings . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4 Thermal Data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5 Electrical Characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5 Electrical characteristics curves . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 12 3 Application information . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 16 3.1 GND protection network against reverse battery . . . . . . . . . . . . . . . . . . . 16 3.1.1 3.1.2 Solution 1: . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 16 Solution 2: . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 17 3.2 3.3 3.4 Load dump protection . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 17 µC I/Os protection: . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 17 Open load detection in off state . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 17 4 Package and PCB thermal data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 19 4.1 4.2 PowerSSO-12 thermal data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 19 PowerSSO-24 thermal data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 21 5 Package information . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 23 5.1 5.2 Package Mechanical . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 23 Packing information . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 25 6 Revision history . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 27 2/28 VND5050J-E / VND5050K-E Block diagram and pin description 1 Figure 1.
