Get to know the S12ZVMAEVB
The S12ZVMA is a
programmable
single-chip solution
for simple loads
needed to be
controlled in the car
remotely via LIN or
PWM command.
Integrated LIN-PHY,
12V-Vreg, and half-
bridge gate driver
allow building
extremely compact
solutions for DC-
motors, solenoids
or resistive loads

Internal Operational Amplifier
•The internal amplifier signals of the S12ZVMA EVB are not correctly routed. In
order to use the internal amplifier of the S12ZVMA some jumpers need to be
open and some external cables connected in order to get the amplifier to work:
•Open jumpers: J32, J34 (3-4, 5-6), J38.
•External cables: Connected from J38 pin 1 to PAD3 of the header ring, J34 pin
3 to PAD1 of the header ring, J34 pin 5 to PAD2 of the header ring.
•The following images show the changes explained above:
