CatalogDescriptionCAD ModelsPin ConfigurationBlock DiagramFeaturesApplication ExampleDatasheetSpecificationsManufacturerUsing WarningFAQDescriptionThe BTS7960 is part of the NovalithIC family containing three separate chips in one package: One p-channel highside MOSFET and one n-channel lowside MOSFET together with a driver IC, forming a fully integrated high current half-bridge. All three chips are mounted on one common leadframe, using the chip on chip and chip by chip technology. The power switches utilize vertical MOS technologies to ensure optimum on state resistance. Due to the p-channel highside switch the need for a charge pump is eliminated thus minimizing EMI. Interfacing to a microcontroller is made easy by the integrated driver IC which features logic level inputs, diagnosis with current sense, slew rate adjustment, dead time generation and protection against overtemperature, overvoltage, undervoltage, overcurrent and short circuit. The BTS 7960 can be combined with other BTS 7960 to form H-bridge and 3-phase drive configurations. CAD Models Figure: PCB Symbol  Figure: Footprint Pin Configuration Figure: Pin Configuration Block Diagram Figure: Block Diagram FeaturesPath resistance of typ. 16 mΩ@ 25 °CLow quiescent current of typ. 7 µA @ 25 °CPWM capability of up to 25 kHz combined with active freewheelingSwitched mode current limitation for reduced power dissipation in overcurrentCurrent limitation level of 43 A typ.Status flag diagnosis with current sense capabilityOvertemperature shut down with latch behaviourOvervoltage lock outUndervoltage shut downDriver circuit with logic level inputsAdjustable slew rates for optimized EMI Application Example Figure: Application Example: H-bridge with Two BTS7960B DatasheetYou can download the datasheet from the link given below:BTS7960B-Datasheet SpecificationsManufacturer:InfineonProduct Category:Motor / Motion / Ignition Controllers & DriversOperating Supply Voltage:5.5 V to 27.5 VOperating Supply Current:3 mAMinimum Operating Temperature:- 40 CMaximum Operating Temperature:+ 150 CMounting Style:SMD/SMTPackage / Case:TO-263-7Packaging:ReelBrand:Infineon TechnologiesProduct Type:Motor / Motion / Ignition Controllers & DriversFactory Pack Quantity:1000Subcategory:PMIC - Power Management ICs ManufacturerInfineon Technologies AG is a German semiconductor manufacturer founded in 1999, when the semiconductor operations of the former parent company Siemens AG were spun off.

A comparator circuit compares two voltages and outputs either a 1 (the voltage at the plus side; VDD in the illustration) or a 0 (the voltage at the negative side) to indicate which is larger. Comparators are often used, for example, to check whether an input has reached some predetermined value.   Why is comparator needed? Comparators are used to find-out deviation of dimensions between a given component being checked and a known datum. The indicated difference in the dimensions is usually small and hence suitable magnification device should be employed to obtain the desired accuracy of measurements.   What is the difference between op-amp and comparator? The difference between an op-amp comparator and a voltage comparator is in the output stage as a standard op-amp has an output stage that is optimized for linear operation, while the output stage of a voltage comparator is optimized for continuous saturated operation as it is always intended to be close to one supply.

The output is also split into channel 1 and channel 2 each capable of driving 15W speakers. The IC also comes in with a built-in mute function and stand-by function.   What is a bridge amplifier? Bridging an amplifier refers to the process of combining two of four channels into one or two channels with half the ohms. The technique has become very popular among many car owners because it allows amplifiers to send out a more powerful mono signal to the subwoofer or speakers.   How does a bridged amplifier work? To operate an amp in bridged mode, a single input signal enters the amplifier and is split into two identical signals. One has its polarity inverted. The original signal is sent to one channel of the amp and the inverted signal is sent to the other channel.

The RF amplifier uses frequency-determining networks to convert the input signal into an output signal that will provide the required response at a given frequency. Why is there a need for an RF amplifier at the input of a receiver?We need to amplify because the RF signals are usually at low voltages. Because of low voltage they are prone to external disturbances. Boosting the signals usually means increasing the voltage and decreasing the current and vice versa. What are the advantages of RF amplifier?The RF amplifier offers greater gain i.e. better sensitivity. It offers better selectivity and hence it has ability to select wanted signals from multiple input signals at the RF receiver. What is the difference between AF and RF?See also RF (radio frequency). AF (audio frequency) (also abbreviated af or a.f.) refers to alternating current ( AC ) having a frequency such that, if applied to a transducer such as a loudspeaker or headset, will produce acoustic waves within the range of human hearing. Where are RF amplifiers used?RF amplifiers that convert a low-power radio frequency signal into a larger signal for driving the antenna of a transmitter. They are used in a wide variety of applications, including wireless communication, TV Transmissions, Radar, and RF heating.
