VNQ5027AK-E Quad channel high side driver with analog current sense for automotive applications Features Max supply voltage V 41V CC Operating voltage range V 4.5 to 36 V CC Max on-state resistance (per ch.) R 27 m PowerSSO-24 ON Current limitation (typ) I 42 A LIMH Applications (1) Off-state supply current I 2 A S All types of resistive, inductive and capacitive 1. Typical value with all loads connected. loads Output current: 42A Suitable as LED driver 3.0 V CMOS compatible input Description Current sense disable Proportional load current sense The VNQ5027AK-E is a monolithic device made using STMicroelectronics VIPower technology. It Undervoltage shut-down is intended for driving resistive or inductive loads Overvoltage clamp with one side connected to ground. Active VCC pin Thermal shutdown voltage clamp protects the device against low energy spikes (see ISO7637 transient Current and power limitation compatibility table). Very low standby current This device integrates an analog Current Sense Protection against loss of ground and loss of which delivers a current proportional to the load VCC current (according to a known ratio) when Very low electromagnetic susceptibility CS DIS is driven low or left open. When CS DIS is driven high, the CURRENT SENSE pin is in a Optimized electromagnetic emission high impedance condition. Output current Reverse battery protection (see Application limitation protects the device in overload schematic on page 20) condition. In case of long overload duration, the In compliance with the 2002/95/EC European device limits the dissipated power to safe level up directive to thermal shut-down intervention. Package: ECOPACK Thermal shut-down with automatic restart allows the device to recover normal operation as soon as fault condition disappears. Table 1.
