• Undervoltage lockout (UVLO)
• Cross-conduction prevention
• Automotive-grade qualification

Benefits:

• Efficiently drives MOSFETs or IGBTs in half-bridge or full-bridge configurations
• Protects power switches from damage due to overcurrent or undervoltage conditions
• Prevents cross-conduction, which can lead to device failure
• Enables precise control of motor speed and torque
• Meets the stringent requirements of automotive applications

The A8958CLBTR is a high-performance gate driver that is designed to drive both high-side and low-side MOSFETs or IGBTs in half-bridge or full-bridge configurations. The wide operating voltage range makes it suitable for a variety of applications. The adjustable dead time allows designers to optimize the switching performance of the power switches. The overcurrent protection and undervoltage lockout features protect the power switches from damage in the event of a fault condition. The cross-conduction prevention feature prevents both the high-side and low-side switches from being turned on simultaneously, which can lead to device failure.

The automotive-grade qualification ensures that the A8958CLBTR can withstand the harsh conditions of automotive environments. Its robust design and comprehensive protection features make it an ideal choice for automotive and industrial applications requiring reliable control of power switches.
