Driver with Open-LED Fault Detect
Features
The MAX16839 programmable current regulator operates
from a 5V to 40V input voltage range and features an
open-drain, constant-current-sink output capable of sinking up to 100mA. The MAX16839 is well suited for automotive applications and other applications that require a
general-purpose linear LED driver. The device directly
withstands automotive load-dump events of up to 45V.
S 5V to 40V Operating Range
An on-board pass element minimizes external component count while providing Q5% output current accuracy.
The MAX16839 includes a dimming input that controls
the duty cycle of the output current, allowing a wide LED
dimming range. In addition, the dimming input functions
as an on/off control of the output current. In multiple LEDstring applications, the dimming input synchronizes the
LED current-sink turn-on, ensuring simultaneous brightness in LED strings.
S LED Open-Fault Detect Latches Off Multiple LED
Additional features include thermal and open-LED
protection and an open-LED fault-detection output. In
multiple LED string applications where all FLTS pins are
connected together, an open-LED detection in one LED
string turns off all the strings simultaneously. Open-LED
protection also features fault memory, to avoid LED flashing during subsequent power-up cycles.
The MAX16839 is available in thermally enhanced, 6–pin
TDFN-EP and 8-pin SO-EP packages and is specified
over the -40NC to +125NC automotive temperature range.

A 51I resistor is connected between SINK and a 6.5V supply to reduce power dissipation during the factory test.
All devices are 100% production tested at TA = +25NC. Limits over temperature are guaranteed by design.
Guaranteed by design and not production tested.
Internal switch resistance is measured with ISINK = 0.95 x ISINK0 (ISINK0 is ISINK at VSINK = 0.9V).
Supply turn-on delay will be measured by rising supply in 6Fs from GND to 12V, and measurement starts when VIN = 4V
(typical UVLO).
Note 7: DIM is kept high to avoid delay due to high capacitance from test setup. In applications, a 30FA pullup current charges
parasitic capacitance at DIM with negligible delay. Ensure that unnecessary capacitance is not added at DIM during the
PCB layout.

High-Voltage, Linear High-Brightness LED
Driver with Open-LED Fault Detect
The MAX16839 programmable current regulator operates from a 5V to 40V input voltage range and features
an open-drain, constant-current-sink output capable of
sinking up to 100mA. The MAX16839 directly withstands
automotive load-dump events of up to 45V.
A single resistor-programmable output current and onboard pass element minimize the number of external
components while providing Q5% output current accuracy.
The MAX16839 includes a dimming input that controls
the duty cycle of the output current, allowing a wide
LED dimming range to be implemented. In addition, the
dimming input functions as an on/off control of the
output current. In multiple LED-string applications, the
dimming input synchronizes the LED current-sink turn-on,
ensuring simultaneous brightness in LED strings.

Additional features include thermal protection and an
open-LED detection output that can turn off multiple LED
strings simultaneously. See Figure 1.
Open-LED Detection and
Fault Event Status Memory
The MAX16839 has an integrated open-LED detection
that reduces external components required to implement
this function. The following conditions enable the openLED detection feature:

Detailed Description
MAX16839
High-Voltage, Linear High-Brightness LED
Driver with Open-LED Fault Detect
The MAX16839 detects an open-LED event when VCS
drops below 30mV for 25µs. When the fault condition is
detected, a 2.8mA current source charges the capacitor between FLTS and ground, up to 15V or to VIN if VIN
is less than 15V. If the voltage on FLTS is greater than
1.65V due to the charge retained in the FLTS capacitor,
the LED driver is turned off. This provides an open-LED
fault-protection feature that can be disabled by connecting FLTS to ground. In a multistring application (Figure
2), where all FLTS pins are connected together, a fault
detected on one channel causes other channels to turn
off as well. The retention capability on the FLTS is dependent on the leakage current and the value of the capacitor
12V
used. If the retention capability is high, the fault condition
could be retained or memorized for a long period after the
supply is turned off.
Thermal Protection
The MAX16839 enters thermal-shutdown mode in the
event of overheating. When the junction temperature
exceeds TJ = +160NC, the internal thermal-protection
circuit turns off the series pass element. The MAX16839
recovers from thermal-shutdown mode when the
junction temperature drops to TJ = +145NC. FLTS does
not assert during an overheating event.

High-Voltage, Linear High-Brightness LED
Driver with Open-LED Fault Detect
FLTS Capacitor
If a fault condition is detected, a 2.8mA current source
charges CFLTS to memorize the fault condition and avoid
flashing during the subsequent power-up cycles. The
choice of the CFLTS is based on the following conditions:
U Fault hold time
dropout voltage of the regulator. If the device is operated below VIN(MIN), the output current may not meet the
full regulation specification (see the Typical Operating
Characteristics).
For applications that require more than 3 LEDs per string
and have slow supply rise time (> 14Fs), FLTS should, in
general, be connected to ground to avoid false triggering of the open-LED protection.
U Board leakage and FLTS leakage
U Input supply voltage, as this affects the maximum
FLTS voltage
U The number of ICs connected together in case of a
multistring application
Use the following equation to calculate the FLTS capacitor (CFLTS):
I
×t
×N
C FLTS = FLTS FLTS
(VFLTS − VFLTH )
where IFLTS is the maximum leakage current through
FLTS, tFLTS is the desired fault retention period, VFLTS
is the typical voltage (minimum of 15V or the supply
voltage) to which CFLTS is charged during a fault event,
VFLTH is the minimum threshold to detect the fault
memory as logic-high, and N is the number of devices in
a multistring application.
Programming the LED Current
The MAX16839 uses a sense resistor to program the
output current sink. To program the LED current, connect
a sense resistor from the current-sense input (CS) to
GND with short traces. The value of the sense resistor
for a given desired current is calculated with the following equation:
PWM Dimming
The MAX16839 includes a PWM dimming input (DIM)
to control the LED brightness. An application of up to a
10kHz signal is recommended at DIM for proper operation. DIM also functions as an active-high enable input.
Driving DIM low turns off the output. Driving DIM high or
leaving DIM unconnected turns on the output.
For VIN > undervoltage-lockout threshold, the MAX16839
activates a 30FA (typ) pullup current at DIM. When VIN <
undervoltage-lockout threshold, the MAX16839 activates
a 1mA pulldown current.
Supply Chopped Dimming
The MAX16839 can do efficient supply chopped
dimming, as it is specially designed for very low startup
delay. The LED current is turned on in 4Fs (typ) after
the supply comes up. The LED current pulse-width
modulates in phase with the supply voltage. Minimize the
input filter capacitor after the chopper circuit for fast rise
and fall times of the input supply.
Power Dissipation
The power dissipation (PD) of the MAX16839 is
determined from the following equation:
PD = (VIN × IIN ) + (VIN − ∑VLED − VCS ) × (ILED × DUTY)
where:
V (V)
R CS (Ω) = CS
ILED (A)
VIN = Supply voltage
IIN = Supply current
where VCS is 203mV (typ) (see the Electrical
Characteristics table).
Input Voltage
For proper operation, the minimum input voltage must
always be:
VIN(MIN) = VCS(MAX) + VFT(MAX) + ∆VDO
where VCS(MAX) is the maximum voltage drop across the
sense resistor RCS, VFT(MAX) is the total forward voltage
of all series-connected LEDs, and DVDO is the maximum
CVLED = Total forward voltage for the LED string
ILED = LED current
VCS = 203mV drop across RCS
DUTY = PWM duty cycle
The MAX16839 thermal specifications are given according to the JEDEC-51 guidelines. Good mechanical/
thermal design practices must be applied to help
maintain the device junction temperature below the
absolute maximum ratings at all times.
