VND5E050KTR-E STMicroelectronics

VND5E050J-E VND5E050K-E Double channel high side driver for automotive applications Features Max supply voltage V 41V CC Operating voltage range V 4.5 to 28V CC Max On-State resistance (per ch.) R 50 m ON Current limitation (typ) I 27 A LIMH PowerSSO-12 PowerSSO-24 (1) Off-state supply current I 2 A S 1. Typical value with all loads connected. Applications General All types of resistive, inductive and capacitive Inrush current active management by loads power limitation Very low standby current Description 3.0V CMOS compatible inputs The VND5E050J-E and VND5E050K-E are Optimized electromagnetic emissions double channel high-side drivers manufactured in Very low electromagnetic susceptibility the ST proprietary VIPower M0-5 technology In compliance with the 2002/95/EC and housed in the tiny PowerSSO-12 and european directive PowerSSO-24 packages. Diagnostic functions The VND5E050J-E and VND5E050K-E are Open Drain status output designed to drive automotive grounded loads On-state open-load detection delivering protection, diagnostics and easy 3V Off-state open-load detection and 5V CMOS-compatible interface with any microcontroller. Output short to Vcc detection Overload and short to ground (power The devices integrate advanced protective limitation) indication functions such as load current limitation, inrush Thermal shutdown indication and overload active management by power limitation, over temperature shut-off with Protections auto-restart and over-voltage active clamp. Undervoltage shutdown A dedicated active low digital status pin is Overvoltage clamp associated with every output channel in order to Load current limitation provide Enhanced diagnostic functions including Self limiting of fast thermal transients fast detection of overload and short-circuit to Protection against loss of ground and loss ground, over temperature indication, short-circuit of V CC to V diagnosis and on & off-state open-load CC Over temperature shutdown with auto detection. restart (thermal shutdown) The diagnostic feedback of the whole device can Reverse battery protected (see Figure 32) be disabled by pulling the STAT DIS pin up, thus Electrostatic discharge protection allowing wired-ORing with other similar devices.
