The IRS20965 features high side and low side independent floating pulse width modulation inputs for dead time control from an external pulse width modulation controller. The anti-breakdown logic of the new IC provides additional protection in the event of a pulse width modulation controller failure. The product also features an overcurrent detection output and 2A gate drive output capability.

Pan Dawei, vice president of sales for IR Asia Pacific, said: "The new chipset is equipped with the IRS20965 digital audio driver IC, which makes the external controller with programming performance and protection more flexible. For example, the new product provides non-shutdown overload protection. Maintain high quality audio performance."

The IRS20965 operates at frequencies up to 800kHz. Other key features include programmable bidirectional overcurrent sensing with self-reset capability, superior noise immunity, ±100 V rating for up to 500W output power, and 3.3V or 5V logic compatibility. enter.

The product is currently accepting bulk orders. The new device complies with the RoHS Directive and Industrial Certification.

Battery Cable

Over time, battery cables have to be replaced due to corrosion or damage. A bad battery cable can cause intermittent starting issues or lack of power to the vehicle, including arcing or power drains.A battery cable consists of multiple stands of wire encased in synthetic material with different types of battery terminals on each end for a reliable connection. Corrosion is the number one cause of battery cable failure, stopping the flow of electricity.
