Table 3 shows the differences.


Packaging differences for the newest motor driver ICs 6 7 Target automotive applications include those in emission systems identified earlier as well as brushed DC motor requirements in body electronics and other vehicle systems as shown in Table 4. Windshield wipers, seatbelt retractors, active grill shutters, convertible top, tailgate, seating, mirrors Addressing Automotive Application Issues The HB and HB motor driver ICs have several built-in features and a few rather straightforward design tips can simplify their use in automotive applications and address previously identified issues of avalanche breakdown protection, ripple reduction, NXP HB2000 Evaluation battery protection, switching noise reduction.

Voltage variations and battery disconnect are among the unique automotive operating conditions that must be addressed for any integrated circuit. NXP HB2000 Evaluation power is interrupted to the power pin input to the HB and HB H-bridge motor driver, the disabled over-voltage protection could cause an unclamped inductive discharge. To prevent electrical overstress of the output drivers, the should not exceed 40 V during this transient condition.


C1 ESR C2 0. Avalanche breakdown protection implementation and ripple reduction. Typically, both a capacitor and an MOV are used, since the capacitor helps reduce the ripple in the NXP HB2000 Evaluation voltage.

The low ESR, high-capacitance capacitor should be selected for the NXP HB2000 Evaluation frequency to reduce the ripple in the system voltage generated while switching. To do this, the user needs to identify the maximum acceptable ripple allowed in the system voltage line.

In those situations, an external, reverse-polarity FET may be used instead of the reverse protection diode to reduce the voltage drop from battery to NXP HB2000 Evaluation and provide reverse battery protection as shown in Figure 5. A capacitor on each output helps reduce noise by reducing voltage peaks. Figure 6 shows the impact of the capacitor on the output voltage OUTX.


The current from the CFB pin can be converted to voltage using a shunt resistor whose value is based on following parameters: Shown in Figure 8, the EVM for the motor driver ICs has a complete manual and software to simplify system design and reduce time-to-market. Freedom development platform Support from a range of NXP and third-party development software with full access to online SDK, tools and reusable code means no downloads, installations or licenses. Towards More Sophisticated Motor Designs NXP HB2000 Evaluation on already stringent requirements compared to a decade or so ago, existing and future regulations for reduced emissions and higher efficiency in automobiles will dictate innovative design changes.
