Dual-Pair LLT with Charge Pump
and High-ESD Protection
General Description
The MAX14569 is a dedicated dual-pair unidirectional
logic-level translator that is ideal for industrial and meter-
ing applications. Voltages VCC and VL set the logic
levels on either side of the device. Logic-high signals
present on the VL side of the device appear as high-
voltage logic signals on the VCC side of the device and
vice versa.
The device has two pairs of logic-level translators in
back-to-back configuration: one logic-level translator
from a low voltage to a high voltage and the other logic-
level translator from a high voltage to a low voltage. The
device also features a high-efficiency charge pump to
boost the battery input, VBAT, to VCC (5V).
The device features an extreme power-saving mode
that reduces supply current to a typical 0.01FA. The
device also features thermal short-circuit protection for
enhanced protection in applications that route signals
externally.
In addition, the device features enhanced high electro-
static discharge (ESD) Human Body Model (HBM) pro-
tection on OUTAVCC, INBVCC, OUTCVCC, and INDVCC
ports up to Q25kV. The MAX14569 is available in a
16-pin QSOP package, and is specified over the -40NC
to +85NC extended temperature range.

Dual-Pair LLT with Charge Pump
and High-ESD Protection
Detailed Description
The MAX14569 is a dedicated dual-pair unidirectional
logic-level translator that is ideal for automatic remote-
metering applications. Externally applied voltage VL
and regulated output voltage VCC set the logic levels on
either side of the device.
The device boosts the VBAT supply input voltage to a
charge-pump-regulated output, VCC. Logic-high signals
present on the VL side of the device appear as a high-
voltage logic signals on the VCC side of the device and
vice versa.
The device has two pairs of logic-level translators in
back-to-back configuration: one logic-level translator
from a low voltage to a high voltage and the other logic-
level translator from a high voltage to a low voltage.
The device features an extreme power-saving mode that
reduces supply current to a typical 0.01FA. The device
also features thermal short-circuit protection on the VCC
side for enhanced protection in applications that route
signals externally.
Level Translation
For proper operation, ensure that 2.3V P VBAT P 5.5V,
1.6V P VL P 5.5V. The device enters low-power shutdown
mode when ENAB = ENCD = GND (see the Functional
Table). In shutdown mode, the INAVL, INBVCC, INCVL,
INDVCC, OUTAVCC and OUTCVCC are in high-imped-
ance mode and the OUTBVL and OUTDVL are pulled
down to GND. The maximum data rate depends heavily
on the load capacitance (see the rise/fall times in the
Typical Operating Characteristics), output impedance of
the driver, and the operating voltage range.
Output Load Requirements
The device is designed to drive a wide variety of load
types including a high capacitive load. To protect the
VCC outputs (OUTAVCC, OUTCVCC) from a harsh
external environment, the VCC outputs are ruggedized
with a high ESD-capable output structure. When the high
capacitive load is connected to the VCC output side, the
current is limited by the charge-pump circuit along with
the output driver impedance. The device is also pro-
tected by the thermal protection.
