CSO

Output of current sense comparator, compatible with TTL logic signal; during

the pin is forced low whereas whenever the OC comparator is triggered (CSI> 0.55 typ.) the pin

latches high.

19

CSI

Input of current sense comparator, it is enabled only during

voltage exceeds the internal threshold, the CSO pin is forced high and the half bridge drivers

are disabled. It exits from this condition by either cycling the Vcc below the UVLO or with

LGI=HGI=low simultaneously.

20

VREF

Voltage reference. During

reference that can be used to supply up to 30mA (during

A small film capacitor (0.22

µF min.), connected between this pin and GND is recommended to

ensure the stability of the generator and to prevent noise from affecting the reference.
