Description
The VNLD5160-E is a monolithic device made
using STMicroelectronics® VIPower® technology,
intended for driving resistive or inductive loads
with one side connected to the battery. Built-in
thermal shutdown protects the chip from
overtemperature and short-circuit. Output current
limitation protects the device in an overload
condition. In case of long duration overload, the
device limits the dissipated power to a safe level
up to thermal shutdown intervention.Thermal
shutdown, with automatic restart, allows the
device to recover normal operation as soon as a
fault condition disappears. Fast demagnetization
of inductive loads is achieved at turn-off.

3.1 MCU I/O protection
ST suggests to insert a resistor (Rprot) in line to prevent the microcontroller I/O pins from
latching up(a). The value of these resistors is a compromise between the leakage current of
microcontroller and the current required by the LSD I/Os (input levels compatibility) with the
latch-up limit of microcontroller I/Os:
Equation 1
I--l--a---0t--c-.--7h---u---p-- ≤ Rprot ≤ -(--V----O----I-H-I-H--μ---C-m----–-a---x-V----I--H----)
