Description :

The UP6281 is a dual, high voltage MOSFET driver optimized for driving two N-Channel MOSFETs in a synchronousrectified buck converter. Each driver is capable of driving a 5000pF load with 30ns transition time. This device combined with uPI multi-phase buck PWM controller forms a complete
core voltage regulator for advanced micro-processors.

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 […]

Features :

1. All-In-One Synchronous Buck Drivers

2. Bootstrapped High-Side Driver

3. Adaptive Anti-Shoot-Through Protection Circuitry

4. 1 PWM Signal Generates both Drivers

5. Tri-State Input for Bridge Shutdown

6. Output Disable Control Turns Off both MOSFETs

7. Under Voltage Lockout for Supply Input

DRV8301 datasheet

 

Description :

The DRV8301 is an automotive gate driver IC for three phase motor drive applications. It provides three half bridge drivers, each capable of driving two N-type MOSFETs, one for the high-side and one for the low side. It supports up to 2.3A sink and 1.7A source peak current capability and only needs a single power supply with a wide range from 6V to 60V. The DRV8301-Q1 uses bootstrap gate drivers with trickle charge circuitry to support 100% duty cycle. The gate driver uses automatic hand shaking when high side FET or low side FET is switching to prevent current shoot through. Vds of FETs is sensed to protect external power stage during overcurrent conditions.

The DRV8301Q1 includes two current shunt amplifiers for accurate current measurement. The current amplifiers support bi-directional current sensing and provide an adjustable output offset of up to 3V.

Features :

1. Slew Rate Control for EMI Reduction

2. Bootstrap Gate Driver With 100% Duty Cycle Support

3. 6- or 3-PWM Input Modes

4. Dual Integrated Current Shunt Amplifiers With Adjustable Gain and Offset

5. Integrated 1.5-A Buck Converter
