Short-circuit Protection
VH and VL output pins incorporate the short-circuit protection function.
When the output pins are short-circuited to allow the large current to flow, IC is latched OFF to interrupt output.
To reset from the interrupted state, set the EN pin to L, then reset it again to H.
Frequency Selection
The charge pump operating frequency can be changed with S0 and S1
logics.
For light load, the reactive load can be reduced by lowering the
operating frequency.
SEL logic also enables synchronous operation with external CLK.
The charge pump is operated with the frequency equivalent to 1/2 of
input CLK.
(The IC internal oscillator is used for the sequence, so that it is
normally ON regardless of SEL.
For minimum 9.4ms after startup with the EN signal set to H, the IC
internal clock is used to operate the charge pump with 1 MHz regardless
of the input of SEL, S0, and S1 pins. After the 9.4ms(min) period, the
charge pump frequency is changed over according to the state of SEL,
S0, and S1 pins. The changeover frequency is set as shown in the table
right.
