1 / 29 page UCC27517 UCC27516 www.ti.com SLUSAY4B – MARCH 2012 – REVISED JUNE 2012 Single Channel High-Speed, Low-Side Gate Driver (with 4-A Peak Source and 4-A Peak Sink) Check for Samples: UCC27517, UCC27516 1 FEATURES APPLICATIONS • Low-Cost, Gate-Driver Device Offering • Switch-Mode Power Supplies Superior Replacement of NPN and PNP • DC-to-DC Converters Discrete Solutions • Companion Gate Driver Devices for Digital • 4-A Peak Source and 4-A Peak Sink Power Controllers Symmetrical Drive • Solar Power, Motor Control, UPS • Fast Propagation Delays (13-ns typical) • Gate Driver for Emerging Wide Band-Gap • Fast Rise and Fall Times (9-ns and 7-ns Power Devices (such as GaN) typical) • 4.5-V to 18-V Single Supply Range DESCRIPTION The UCC27516 and UCC27517 single-channel, high- • Outputs Held Low During VDD UVLO (ensures speed, low-side gate driver devices are capable of glitch free operation at power-up and power- effectively driving MOSFET and IGBT power down) switches. Using a design that inherently minimizes • TTL and CMOS Compatible Input Logic shoot-through current, UCC27516 and UCC27517 Threshold (independent of supply voltage) are capable of sourcing and sinking high, peak- • Hysteretic Logic Thresholds for High Noise current pulses into capacitive loads offering rail-to-rail drive capability and extremely small propagation Immunity delay typically 13 ns. • Dual Input Design (choice of an inverting (IN- pin) or non-inverting (IN+ pin) driver The UCC27516 and UCC27517 provides 4-A source, 4-A sink (symmetrical drive) peak-drive current configuration) capability at VDD = 12 V. – Unused Input Pin can be Used for Enable or Disable Function The UCC27516 and UCC27517 is designed to operate over a wide VDD range of 4.5 V to 18 V and • Output Held Low when Input Pins are Floating wide temperature range of -40°C to 140°C. Internal • Input Pin Absolute Maximum Voltage Levels Under Voltage Lockout (UVLO) circuitry on VDD pin Not Restricted by VDD Pin Bias Supply holds output low outside VDD operating range. The Voltage capability to operate at low voltage levels such as • Operating Temperature Range of -40°C to below 5 V, along with best in class switching characteristics, is especially suited for driving 140°C emerging wide band-gap power switching devices • 5-Pin DBV (SOT-23) and 6-Pin DRS (3 mm x 3 such as GaN power semiconductor devices. mm WSON with exposed thermal pad) Package Options 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
