Description

Card Supply Voltage

CVCC

8 kV+

PWR

CVCC is the programmable voltage output for the Card interface.

It must be connected to external decoupling capacitors (see page 34 and page 36).

Card Supply Voltage

CVCCin

This pin must be connected to CVCC.

Digital Supply Voltage

Is internally generated and used to supply the digital core.

DVCC

EVCC

3 kV+

PWR

This pin has to be connected to an external capacitor of 100 nF and should not be

connected to other devices.

Extra Supply Voltage (Microcontroller power supply)

EVCC is used to supply the internal level shifters of host interface pins.

EVCC voltage can be supplied from the external EVCC pin connected to the host power

supply.

3 kV+

8 kV+

If EVCC cannot be connected to the host power supply, it must be tied to an external

capacitor. EVCC voltage can be generated internally by an automatic follow up of the

logic high level on the I/O pin. In this configuration, connect a 100 nF + 100kOhms in

parallel between EVCC pin and VSS pin.

DC/DC Ground

CVSS

VSS

GND

CVSS is used to sink high shunt currents from the external coil.

Ground

Note:

ESD Test conditions: 3 positive and 3 negative pulses on each pin versus GND. Pulses generated

according to Mil/STD 883 Class3. Recommended capacitors soldered on CVCC and VCC pins.
