It prevents appearance of unexpected impulses or oscillation on the FG/RD output signal due to broken coil (i.e. open connection) or short connection between OUT1 or OUT2 to ground. A decoupling capacitor from 100nF or higher should be placed between the VDD point (fan common node) and IC ground. It reduces the risk of electrical over-stress damage to ground bouncing when plugging/unplugging the fan connector.

Based on mixed-signal CMOS design, the device includes Hall-effect sensor with offset cancellation scheme, voltage regulator, digital logic and power output drivers in a single package. The MLX90285-FG version has an open-drain tachometer FG output that follows the Hall signal. This signal is used by hardware monitoring system to determine the rotation speed of the fan. In the MLX90285-RD version, the open-drain alarm output RD is a safety signal which allows detecting if the fan rotates or not. It is active low during normal spinning of the motor. It goes high when the magnetic flux switching frequency drops below nearly 1.15Hz (35RPM for 2 pole-pair fan) The built-in locked rotor protection automatically shuts off the coil current when the rotor is mechanically blocked for more than 0.43 second. The fan tries to restart every 3 seconds until the rotor is released. This on/off cycling reduces the average current by factor of about 7. This protection prevents the fan to be overheated or damaged. The device is based on the Melexis patented “no-VDD” design which removes the need of separate supply voltage pin for two-coil fan. During operation, the power outputs are always operating as complementary, meaning also that one power output is kept inactive while the other is active. Melexis cleverly turned this fact into benefit as “No-VDD” devices such as MLX90285 recover the power supply through the inactive power output pin. Therefore, a separate supply voltage pin is not required anymore and the device including logical output FG/RD can fit into a small 4-pin through-hole package VK. In the application, the “No-VDD” design inherently isolates the IC behind the fan coils. Without direct output to the external environment, the device is best protected against ESD and over-voltage issue on the power supply voltage line. 6 7 FG state is only valid during normal operation. In locked rotor protection, FG signal is high The magnetic pole is applied facing the branded side of the package 3901090285 Rev. 005 Page 5 of 14 DataSheet Aug/14 MLX90285 24V Low Noise Two-Coil Fan Driver 10 Unique Features 10.1 Active Soft Switching The use of the Melexis Soft Switching techniques in the US168/169 and US651/661 has already proven its efficiency to noticeably reduce electrical and acoustic noise by precisely control the output slope duration on the fan coil. The US168/168 is the first generation with fixed output slope duration and the US651/661 is the second generation with possibility for the user to fine-tune the slope duration via an external pin. The MLX90285 represents the third generation of soft switching device as it goes even a step further into intelligence and smart driving. It mainly combines the major advantage of each previous generation: Adjustable Slope Control best balance between motor performance and acoustic/electrical noise No need of external component for slope control cost efficiency and simplicity “Adjustable without external component” is possible as the device automatically determine the slope duration depending on the fan rotation speed. The MLX90285 determines the fan rotation speed by measuring the half output switching period from the magnetic field signal. The output slope duration is extrapolated by measuring the duration from the falling edge on OUT1 to the cross over with OUT2. The result is processed to determine the actual Output Slope Duration to Torque Period Ratio (SLRATIO = 2 . tSLOPE / TOUT ), leading to two possible options: If SLRATIO < 6.25% (typical), the slope duration should be increased If SLRATIO > 6.25% (typical), the slope duration should be decreased The Digital Slope Duration Control register is incremented or decremented accordingly, thus updating the slope duration value for both outputs OUT1 and OUT2, prior the next rising slope occurring on OUT1.

(N0 - 1) (= REF . 52 = 0.29) 1 - All values in green are arbitrary and just given for example purpose 2 - Condition example: 4000RPM, 2-pole pair rotor magnet, initial slope duration = 0.3ms, target SLRATIO = 6.25% Picture 1 – Active Soft Switching Operation Principle 3901090285 Rev. 005 Page 6 of 14 DataSheet Aug/14 MLX90285 24V Low Noise Two-Coil Fan Driver The Slope Control provides smooth change in the coil current and allows reducing both electrical and acoustic noise. In addition, the MLX90285 slope generation is processed upon reaching a precise magnetic threshold B OP/BRP. Unlike other fan driver using the rotor magnetic field amplitude which might lead to difficulty in adequate rotor magnet magnetisation, the Melexis solution provides best results with different fan size with weaker or stronger rotor magnet. 10.2 Best Performance to Noise compromise The MLX90285 features a typical 6.25% ratio between slope duration over the torque period, proportional to the fan rotation speed. This value is controlled to provide the best compromise between fan performance (rotation speed and current consumption) and acoustic noise. Increasing this ratio mainly lowers the motor efficiency while decreasing this ratio removes the low noise benefit. SLRATIO Output Slope Duration Low Performance 408us Performance High Performance Low Noise 6.25% Acoustic Noise Medium Performance High Noise 140us 2300 2300 Rotation speed (RPM) Rotation speed 6700 6700 Picture 2 – Slope Duration to Torque Period Ratio effect The device keeps this ratio constant within a large rotation speed range from 2300RPM to 6700RPM (2-pole pair fan). Therefore, the device automatically adjusts its low noise specification to a given cooling application requirements. 10.3 Two-Stage Thermal protection The use of soft switching through linear slope control leads to an increase of the IC junction temperature . As a result, using long slope and high output current can result in reaching the thermal protection threshold and so shut off the device to prevent overheating. In the application, it would stop a low noise cooling fan in an environment where cooling is a required due to high temperature. The MLX90285 is the first fan driver to integrate a Two-Stage Thermal Protection. st When the IC junction temperature exceeds a 1 thermal threshold TSD1 ON (140°C typical), the slope duration are unconditionally divided to half the actual value. The immediate effect is a reduction of the average power dissipation, hence it stabilizes or even starts reducing the IC junction temperature so the cooling fan continues rotating to provide airflow in a system. The slope duration is back to normal when the junction temperature decreases below TSD1 OFF (120°C typical). However, in case the reduction of the slope duration is not enough to stop the junction temperature increase, the device has nd a 2 thermal threshold TSD2 ON (160°C typical) which then shuts-off the IC to prevent over-heating. All the outputs OUT1, OUT2 and FG/RD goes to high level and stay in this state until the junction temperature decreases below TSD2 OFF (140°C typical). 3901090285 Rev. 005 Page 7 of 14 DataSheet Aug/14 MLX90285 24V Low Noise Two-Coil Fan Driver 11 Performance Graphs 11.1 RDSON vs. TJ 11.2 RDSON vs. VDD 6 6 5.5 5.5 5 5 4.5 4.5 4 Ron(ohms) Ron (ohms) 4 3.5 3 2.5 3.5 3 2.5 2 2 1.5 1.5 Tj= -40○C Tj= 25○C Ron, VDD=5V 1 Tj= 150○C 1 Ron, VDD=24V 0.5 0.5 0 0 -40 -20 0 20 40 60 80 100 120 140 4 160 6 8 10 12 14 Tj (○C) 11.3 Magnetic parameters vs. TJ 18 20 22 26 28 30 28 30 6 5 5 4 4 3 Magnetic Field(mT ) 3 2 1 0 -1 2 1 0 -1 Bop, Tj= -40oC -2 -2 Bop, Tj= 25○C Bop, Tj= 150○C Brp, Tj= -40○C Brp, Tj= 25○C Brp, Tj= 150○C -3 -3 Bop,VDD=5V -4 -4 Bop,VDD=24V Brp,VDD=5V Brp,VDD=24V -5 -5 -6 -6 -40 -20 0 20 40 60 80 100 120 140 4 160 6 8 10 12 14 16 18 20 22 24 26 VDD (Volts) T j (○C) 11.5 IDD vs. TJ 11.6 IDD vs. VDD 4 4 3.5 3.5 3 3 2.5 IDD(mA) 2.5 IDD (mA) 24 11.4 Magnetic parameters vs. VDD 6 Magnetic Field(mT ) 16 VDD (Volts) 2 2 1.5 1.5 1 1 IDD, Tj= -40○C IDD, Tj= 25○C IDD, VDD= 5V 0.5 0.5 IDD, VDD= 24V 0 IDD, Tj= 150○C 0 -40 -20 0 20 40 60 80 100 120 140 160 Tj (oC) 3901090285 Rev. 005 4 6 8 10 12 14 16 18 20 22 24 26 28 30 VDD (Volts) Page 8 of 14 DataSheet Aug/14 MLX90285 24V Low Noise Two-Coil Fan Driver 11.7 VOL vs TJ 11.8 Power dissipation vs. TA 1 DC - Rth=150degC/W - PDm ax=833m W TA = 25degC 0.9 VK - Rth=200degC/W - PDm ax=625m W 400 0.8 Allowed power dissipation (W) FG/RD pin Output Saturation Voltage,(mV) 500 300 200 VA - Rth=170 degC/W - PDm ax=735m W 0.7 0.6 0.5 0.4 0.3 100 0.2 Vdson, VDD=5V,Iol= 10mA Vdson, VDD=24V,Iol= 10mA TJ MAX = 150degC 0.1 0 0 -40 -20 0 20 40 60 80 100 120 140 160 -40 Tj (○C) 3901090285 Rev. 005 -20 0 20 40 60 80 100 120 140 160 T j (○C) Page 9 of 14 DataSheet Aug/14 MLX90285 24V Low Noise Two-Coil Fan Driver 12 Standard information regarding manufacturability of Melexis products with different soldering processes Our products are classified and qualified regarding soldering technology, solderability and moisture sensitivity level according to following test methods: Reflow Soldering SMD’s (Surface Mount Devices) IPC/JEDEC J-STD-020 Moisture/Reflow Sensitivity Classification for Nonhermetic Solid State Surface Mount Devices (classification reflow profiles according to table 5-2) EIA/JEDEC JESD22-A113 Preconditioning of Nonhermetic Surface Mount Devices Prior to Reliability Testing (reflow profiles according to table 2) Wave Soldering SMD’s (Surface Mount Devices) and THD’s (Through Hole Devices) EN60749-20 Resistance of plastic- encapsulated SMD’s to combined effect of moisture and soldering heat EIA/JEDEC JESD22-B106 and EN60749-15 Resistance to soldering temperature for through-hole mounted devices Iron Soldering THD’s (Through Hole Devices) EN60749-15 Resistance to soldering temperature for through-hole mounted devices Solderability SMD’s (Surface Mount Devices) and THD’s (Through Hole Devices) EIA/JEDEC JESD22-B102 and EN60749-21 Solderability For all soldering technologies deviating from above mentioned standard conditions (regarding peak temperature, temperature gradient, temperature profile etc) additional classification and qualification tests have to be agreed upon with Melexis.
