 Simple single IC application board dedicated
for VNQ7140AJ
 Provides electrical connectivity and thermal
heat-sinking for easy prototyping
 General device features
 Quad channel smart high side driver
with analog feedback
 Very low standby current
 Compatible with 3 V and 5 V CMOS
outputs
 Diagnostic functions
 Multiplexed analog feedback of: load
current with high precision proportional
current mirror, V_CC supply voltage and
TCHIP device temperature
 Overload and short to ground (power
limitation) indication
 Thermal shutdown indication
 OFF-state open-load detection
 Output short to V_CC detection
 Sense enable/disable
 Protections
 Undervoltage shutdown
 Overvoltage clamp
 Load current limitation
 Self limiting of fast thermal transients
 Configurable latch-off on
overtemperature or power limitation
with dedicated fault reset pin
 Loss of ground and loss of V_CC
 Reverse battery with external
components
 Electrostatic discharge protection
Application
Typical applications are all types of automotive
resistive, inductive and capacitive loads.
