Notes
a. Refer to PROCESS OPTION FLOWCHART for additional information.
b. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
c. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum.
d. To supply the output current of 10 mA on a dc basis, an external 13-V supply must be connected between the CAP pin and the S1 pin with the
negative terminal of the supply connected to S1. This is not needed in an actual application because output currents are supplied by the
C
BOOT
capacitor. Voltage specified with respect to V+.
e. For testing purposes, the 10-mA load current must be supplied by an external current source to the V
DD
pin to avoid pulling down the V
DD
supply.
f. Internally generated voltage for reference only.
g. V
CAP
= (V+) + (V
DD
)
Notes
a. FAULT output retains previous state until ENABLE rising edge.
b. Latch FAULT condition, reset by ENABLE rising edge.
c. V
DD
is an internally generated low-voltage supply
