R 50 m ON Current limitation (typ) I 19 A LIMH Applications (1) Off-state supply current I 2A S All types of resistive, inductive and capacitive 1. Typical value with all loads connected loads General features Inrush current active management by Description power limitation The VNQ5050K-E is a monolithic device made Very low standby current using STMicroelectronics VIPower M0-5 3.0 V CMOS compatible input technology. It is intended for driving resistive or Optimized electromagnetic emission inductive loads with one side connected to Very low electromagnetic susceptibility ground. Active V pin voltage clamp protects the CC device against low energy spikes (see ISO7637 In compliance with the 2002/95/EC transient compatibility table). European directive Diagnostic functions The device detects open load condition both in on and off-state, when STAT DIS is left open or Open drain status output driven low. Output shorted to Vcc is detected in On-state open load detection the off-state. Off-state open load detection When STAT DIS is driven high, the STATUS pin Thermal shutdown indication is in a high impedance condition. Protection Output current limitation protects the device in Undervoltage shutdown overload condition. In case of long overload Overvoltage clamp duration, the device limits the dissipated power to Load current limitation a safe level up to thermal shutdown intervention. Self limiting of fast thermal transients Thermal shutdown with automatic restart allows Protection against loss of ground and loss the device to recover normal operation as soon as of V CC the fault condition disappears.
