Application Examples The following sections show typical application examples [1]. 4.1. Single DC-Motor Drive In this sample application the IC can realize the driving of a DC motor via an external relay bridge. Speed, position sensing and anti trap or block detection are done by means of external Hall latches connected to a timer capture unit. The Hall sensors are switched off during standby mode via a switch-able battery voltage output. Additionally Relay contact monitoring can done by checking the voltages over it.

Single DC Motor Drive with soft start / stop For some applications it might be necessary: • To control the motor speed especially during start / stop, • To have an independent switching channel in case the relay “hangs”, • To switch the power via the power transistor and to increase with this the life time of the relay contacts • To monitor the motor current (current sensing and over current shut off). This application requires then also a reverse polarity protection in the power path. Following application diagram shows the practical realization in principle: VBAT VS VBAT RTG VDDA VDDD GNDCAP AD1 PS Hall sensor TC1 LIN LIN KEY0 KEY1 KEY2 KEY3 KEY4 KEY5 KEY6 KEY7 OSC1 OSC2 GNDD GNDA GNDL MLX81150 TC2 REL1 M GNDH REL2 PWM1 PWM2 SENSE1 SENSE2 TI1 TI2 TO GNDCAP Figure 2- Principle application diagram showing a common relay driver controlled by external switches and LIN bus, with soft start / stop and motor current sense Page 12 of 21 REV. 19 APRIL 2020 Product Abstract MLX81150 LIN-Slave for relay and DC motor control 4.3. Single DC motor drive in FET controlled full bridge applications By adding some external additional circuitry, the IC will also allow to drive DC motors in full bridge applications. Position, speed and direction sensing is done via external Hall latches. By having one PWM on the low side path of the half bridge and the inverse PWM (with programmable interlock delay in the high side path) the p channel can be actively switched on in case the current wheels out. Same is for the n-channel Transistor. The other side of the full bridge is then statically switched on or off.

LED-Lamp driver, switch mode power supply In this application the MLX81150 drives a LED lamp with several high power LEDs in a DC-DC converter configuration. The module itself is controlled via the LIN bus. The current in the LED is regulated to a given value. Adjusting PWM frequency and PWM ratio allows controlling the transformer in a very efficient way from EMC perspective as well as from energy point of view.

MLX81150 in 1- and 2- phase BLDC (brush less DC) Motor control applications BLDC motors are used today in several permanent running automotive applications. 1- and 2-phase BLDC motors are applied in several auxiliary applications as small pumps and blowers. In case these pumps request a LIN or PWM interface connection, the MLX81150 is a perfect solution for that. The commutation information for the brush less DC motors is provided by a hall switch/latch reacting on positive and negative magnet field of the permanent magnet rotor.

Key inputs with different wetting currents in active and sleep configuration Depending on different application requests for the key inputs it might be necessary to use in active mode relatively high wetting currents for the external switches. These currents will be provided by external pull up / pull down resistors. The IC will read the switches then with suitable threshold levels. In SLEEP MODE relatively low wetting currents are necessary. These currents will be provided by external pull up / pull down resistors. Wake up will be then just with a rising or falling edge of the incoming signal.
