MAX15500/MAX15501
18 _____________________________________________________________________________________
Output Open Load
The open-circuit error bit activates when VOUT is within
30mV of AVDDO or AVSSO and there is no short-circuit
current in current mode for longer than 260ms. This error
activates the intermittent bit in the error register if the
error goes away before the error register is read.
Internal Overtemperature
The MAX15500/MAX15501 enter standby mode if the die
temperature exceeds +150NC and the overtemperature
protection is enabled as shown in Table 6. When the die
temperature cools down below +140NC, the error regis-
ter must be read back twice to resume normal operation.
The devices provide a 10NC hysteresis.
Brownout
The brownout-error bit activates when the supply voltage
(VAVDD or VAVSS) falls below the brownout threshold.
The threshold is programmable between Q10V to Q24V
in 2V steps. See Table 6 for details. The MAX15500/
MAX15501 provide a 2% hysteresis for the brownout
threshold. The accuracy of the threshold is typically
within 10%. During power-up, ERROR can go low and
the brownout register is set. Users need to read out the
error register twice to clear all the error register bits and
reset ERROR to high.
Output Protection
The MAX15500/MAX15501 supply inputs (AVDD, AVDDO,
AVSS, and AVSSO) and sense inputs (SENSERN,
SENSERP, SENSEVN, and SENSEVP) are protected
against voltages up to Q35V with respect to AGND. See
the Typical Operating Circuit/Functional Diagram for the
recommended supply-voltage connection.
SPI Interface
Standard SPI Implementation
The MAX15500/MAX15501 SPI interface supports daisy-
chaining. Multiple MAX15500/MAX15501 devices can
be controlled from a single 4-wire SPI interface. The
MAX15500/MAX15501 feature dual CS_ inputs and
an added digital output, READY, that signals when
the devices finish processing the SPI frame. CS1 and
CS2 are internally OR-ed. Pull both CS1 and CS2 to
logic-low to activate the MAX15500/MAX15501. For a
daisy-chained application, connect the CS1 input of
all of the devices in the chain to the CS driver of the
microcontroller. Connect the CS2 input of the first device
to ground or to the CS driver of the microcontroller.
Connect CS2 of the remaining devices to the READY
output of the preceding device in the chain. The READY
output of the last device in the chain indicates when
all slave devices in the chain are configured. Connect
the READY output of the last device in the chain to the
microcontroller. Use the open-drain ERROR output as a
wired-OR interrupt. See Figures 3 to 6.
