DESCRIPTIONThe VNQ5050K-E is a monolithic device made
using STMicroelectronics VIPower technology. It
is intended for driving resistive or inductive loads
with one side connected to ground. Active VCC pin
voltage clamp protects the device against low
energy spikes (see ISO7637 transient
compatibility table).

Table 9. Protections (see note 3)Note:3. To ensure long term reliability under heavy overload or short circuit conditions, protection and related diagnostic signals must be
used together with a proper software strategy. If the device is subjected to abnormal conditions, this software must limit the duration
and number of activation cycles
