GENERAL DESCRIPTION
The uP6281 features adaptive anti-shoot-through protection that prevents cross-conduction of the external MOSFET while maintains minimum deadtime for optimized efficiency. Both gate drives are turned off by pulling low OD# pin or high-impedance at PWM pin, preventing rapid output capacitor discharge during system shutdowns. Other feature is supply input under voltage lockout. The uP6281 is available in thermal enhanced PSOP-8L or WDFN3x3-8L packages. Bootstrapped High-Side Driver Adaptive Anti-Shoot-Through Protection Circuitry 1 PWM Signal Generates both Drivers Tri-State Input for Bridge Shutdown Output Disable Control Turns Off both MOSFETs Under Voltage Lockout for Supply Input PSOP-8L or WDFN3x3-8L Packages RoHS Compliant and Halogen Free FEATURES
