Preliminary Technical Data
AD5100
Power Requirements
Internal Power
The AD5100 internal power V
REG
is derived from V
1MON
and
V
2MON
is used to turn AD5100 on and off with a different
behavior depending on the V
2MON
monitoring mode
selection. By default, in the V
2MON
level sensitive mode, the
AD5100 turns on when the voltage at V
2MON
rises above the
logic threshold V
2MON_ON
, When V
2MON
falls below the logic
Rev. PrJ | Page 19 of 32
threshold V
2MON_OFF
, AD5100 will trun off 2 seconds after
SHDN
is deasserted. Note that AD5100 requries 5 us to start
up and that
V
1MON
must be applied before V
2MON
.
The extension
of the AD5100 turn-off attempts to allow the system to
complete any housekeeping tasks before the system is
powered off. Figure 17 shows the defaulted V
2MON
and V
REG
waveforms.

Timing Diagrams (Default)
If the Pulse-Sensitive V

Mode is selected instead, the
AD5100 will not turn off when V
2MON
returns to a logic low.
In this mode, once the part has been powered on, it can only
V
OTP
A 6V supply voltage is needed only during OTP fuse
programming. This voltage should be provided by an
external source during factory programming and should have
6V/200mA driving capability. The OTP programming
duration depends on the numbers of programming fuses
with maximum duration of 10ms. V
OTP
is not required for
normal operation. The V
OTP
has dual functions, it is used for
programming the non-volatile memory fuse arrays as well as
serving as a compensation network for internal power
stability. As a result, a bypass capacitor must be connected at
V
OTP
pin at all times. A low ESR 10uF tantalum capacitor is
recommended.
be power-down by an I2C power down instruction or by
eliminating the supply on V
1MON
pin. This feature is for the
applications that use a wake up signal.
Figure 18. Power Supply Requirement
AD5100 achieves the OTP function through blowing internal
fuses. Users should always apply the 6 V one-time program
voltage requirement at the first fuse programming attempt.
Failure to comply with this requirement may lead to a change in
the fuse structures, rendering programming inoperable.
Care should be taken when SCL and SDA are driven from a low
voltage logic driver.
