(1)Component qualification in accordance with JEDEC and industry standards to ensure reliable operation over an extended temperature range. This includes, but is not limited to, Highly Accelerated Stress Test (HAST) or biased 85/85, temperature cycle, autoclave or unbiased HAST, electromigration, bond intermetallic life, and mold compound life. Such qualification testing should not be viewed as justifying use of this component beyond specified performance and environmental limits.

DESCRIPTION/ORDERING INFORMATION

The UC2625 motor controller integrates most of the functions required for high-performance brushless dc motor control into one package. When coupled with external power MOSFETs or Darlingtons, this device performs fixed-frequency PWM motor control in either voltage or current mode while implementing closed loop speed control and braking with smart noise rejection, safe direction reversal, and cross-conduction protection.

Although specified for operation from power supplies between 10 V and 18 V, the UC2625 can control higher voltage power devices with external level-shifting components. The UC2625 contains fast, high-current push-pull drivers for low-side power devices and 50-V open-collector outputs for high-side power devices or level shifting circuitry.

The UC2625 is characterized for operation over the military temperature range of -55°C to 125°C.
