High-Voltage, 100mA/200mA Adjustable Linear
High-Brightness LED Drivers with PWM Dimming
The MAX16815/MAX16828 current regulators operate
from a 6.5V to 40V input voltage range and deliver up
to 100mA (MAX16815) or 200mA (MAX16828) to highbrightness LED (HB LED) loads. The output current is
adjusted by using an external current-sense resistor in
series with the LEDs. The MAX16815/MAX16828’s dimming input allows wide-range “pulsed” PWM operation.
An on-board pass element minimizes external components while providing ±3.5% output-current accuracy.
The MAX16815/MAX16828 are available in a thermally
enhanced, 3mm x 3mm, 6-pin TDFN package with
exposed pad and in an 8-pin SO package with
exposed pad; they are specified over the automotive 40°C to +125°C temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 2: All devices are 100% production tested at TA = +25°C. Limits over the operating temperature range are guaranteed by
design.
Note 3: Resistors were added from OUT to CS+ to aid with power dissipation.
Note 4: Dropout is measured as follows:
Connect RO from OUT to CS+. Connect RSENSE = 2Ω (MAX16815) from CS+ to GND (for TDFN) or from CS+ to CS- (for
SO). Set VIN = 12V (record VOUT1 = VOUT). For VIN = 40V, use RO = 360Ω; for VIN = 6.5V, use RO = 56Ω.
Reduce VIN until VOUT = 0.97 x VOUT1 (record as VIN2 and VOUT2). ΔVDO = VIN2 - VOUT2.
Note 5: Dropout is measured as follows:
Connect RO from OUT to CS+. Connect RSENSE = 1Ω (MAX16828) from CS+ to GND (for TDFN) or from CS+ to CS- (for
SO). Set VIN = 12V (record VOUT1 = VOUT). For VIN = 40V, use RO = 180Ω; for VIN = 6.5V, use RO = 27Ω.
Reduce VIN until VOUT = 0.97 x VOUT1 (record as VIN2 and VOUT2). ΔVDO = VIN2 - VOUT2.
Note 6: IV5 = 0mA.
Note 7: tON time includes the delay and the rise time needed for IOUT to reach 90% of its final value. tOFF time is the time needed for
IOUT to drop below 10%. See the Typical Operating Characteristics. tON and tOFF are tested with 100Ω (MAX16815) or 51Ω
(MAX16828) from OUT to CS+.
Note 8: Current regulation varies with V5 load (see the Typical Operating Characteristics).
Note 9: Thermal shutdown does not function if V5 is shorted to ground.

Applications Information
+5V Regulator
Programming the LED Current
The MAX16815/MAX16828 include a fixed +5V output
regulator that delivers up to 4mA of load current
throughout the 6.5V to 40V input voltage range.
Connect a 0.1µF compensation capacitor from V5 to
ground. Shorting V5 to ground disables the thermal
shutdown. V5 stays on during PWM dimming.
The MAX16815/MAX16828 use a sense resistor across
CS+ and GND for the TDFN package or across CS+
and CS- for the SO package, to set the LED current.
The LED current is given by ILED = VRSNS/RSENSE.
Thermal Protection
The MAX16815/MAX16828 enter a thermal-shutdown
mode in the event of overheating. This typically occurs
in overload or output short-circuit conditions. If the
junction temperature exceeds TJ = +159°C (typ), the
internal thermal-protection circuitry turns off the series
pass device. The MAX16815/MAX16828 recover from
thermal-shutdown mode once the junction temperature
drops by 24°C (typ). The devices therefore protect
themselves by thermal cycling in the event of a shortcircuit or overload condition. Shorting V5 to ground disables the thermal shutdown.
Input-Voltage Considerations
For proper operation, the minimum input voltage must
always be:
VIN(MIN) ≥ VRSNS(MAX) + VFT(MAX) + ΔVDO(MAX)
where VFT(MAX) is the total forward voltage of all series
connected LEDs. The minimum operating voltage of the
device is +6.5V. The device operates below +6.5V;
however, output current may not meet the full regulation
specification (see the Typical Operating Characteristics)
and the V5 regulator will drop below 5V.
Low-Frequency PWM Dimming
at the Output
Provide a pulse to the dimming input (DIM) of the
MAX16815/MAX16828 to produce a PWM output.
Alternatively, connect DIM to IN and pulse IN.

Figure 1 shows PWM dimming operation for the
MAX16815/MAX16828 with an ICM7555 timer. The
ICM7555 provides adjustable duty cycle using two
external resistors and a capacitor. In TAIL operation,
the output of the ICM7555 feeds into DIM and lights up
the LEDs. The LED’s brightness depends on the duty
cycle of the ICM7555. When VSTOP is present, DIM is
pulled up to VSTOP. The PWM dimming operation is disabled and the LEDs light up to full brightness. See the
ICM7555 data sheet for formulas to calculate the dimming frequency and the duty cycle.

LED Current Thermal Foldback
With a minimum number of external components, the
MAX16815/MAX16828 provide LED current thermal
foldback using a negative temperature coefficient
(NTC) thermistor. Figure 2 shows a thermistor connected to V5 and the CS+ of the MAX16815/MAX16828. As
the temperature increases, the voltage drop across R2
increases, causing the LED current to decrease.
ILED = [VRSNS - (R2 / RT) (VV5 - VRSNS)]/R1
Figure 2. LED Current Thermal Foldback with an NTC
Thermistor
Other Applications
STOP operation, Q1 turns on and the output current is
set by a parallel combination of R1 and R2. Figure 4
shows an application circuit with the MAX16815/
MAX16828 using a single BJT to provide high output
current. For proper operation:
VIN(MIN) > VCESAT(MAX) + VFT(MAX) + VRSNS
The application circuit in Figure 3 implements a twolevel brightness current for TAIL/STOP lights. In TAIL
operation, Q1 is off and R1 sets the output current. In
where VCESAT(MAX) is the maximum saturation voltage
of the external BJT and VFT(MAX) is the total forward
voltage of all series connected LEDs.
