Table 2. Pin Functions (continued)
N.
Pin
Function
18
CSO Output of current sense comparator, compatible with TTL logic signal; during operating mode,
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 operating mode; when the pin
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 operating mode an internal generator provides an accurate voltage
reference that can be used to supply up to 30mA (during operating mode) to an external circuit.
A small film capacitor (0.22µF min.), connected between this pin and GND is recommended to
ensure the stability of the generator and to prevent noise from affecting the reference.
