Typical value with all loads connected. Applications ■ ■ Main – Inrush current active management by power limitation – Very low standby current – 3.0 V CMOS compatible input – Optimized electromagnetic emission – Very low electromagnetic susceptibility – In compliance with the 2002/95/EC European directive ■ Description Diagnostic functions – Open drain status output – On-state open load detection – Off-state open load detection – Thermal shutdown indication Protections – Undervoltage shutdown – Overvoltage clamp – Output stuck to VCC detection – Load current limitation – Self limiting of fast thermal transients – Protection against loss of ground and loss of VCC – Thermal shutdown Table 1. Device summary ■ All types of resistive, inductive and capacitive loads The VND5050K-E and VND5050J-E are monolithic devices made using STMicroelectronics VIPower M0-5 technology. they are intended for driving resistive or inductive loads with one side connected to ground. Active VCC pin voltage clamp protects the devices against low energy spikes (see ISO7637 transient compatibility table). The devices detect 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 devices in overload condition. In case of long overload duration, the devices limit the dissipated power to a safe level up to thermal shutdown intervention. Thermal shutdown with automatic restart allows the devices to recover normal operation as soon as fault conditions disappear.
