| Description | LM2005 107-V, 0.5-A, 0.8-A Half-Bridge Driver with 8-V UVLO and Integrated Bootstrap Diode |
# LM2005 Half-Bridge Driver
## Features
️· Drives two N-channel MOSFETs in half-bridge configuration
️· Integrated bootstrap diode
️· 8-V typical undervoltage lockout (UVLO) on GVDD
️· 107-V absolute maximum voltage on BST
️· -19.5-V absolute maximum negative transient voltage handling on SH
️· 0.5-A / 0.8-A peak source/sink currents
️· 115-ns typical propagation delay
## Applications
️· Brushless-DC (BLDC) motors
️· Permanent magnet synchronous motors (PMSM)
️· Cordless vacuum cleaners
️· Cordless garden and power tools
️· E-bikes and e-scooters
️· Battery test equipment
️· Offline uninterruptible power supply (UPS)
️· General-purpose MOSFET or IGBT driver
## Description
The LM2005 is a compact, high-voltage gate driver for synchronous buck or half-bridge configurations. It includes an integrated bootstrap diode to reduce system cost and size. It offers robust performance with -1V and -19.5V transient voltage handling. UVLO protection is provided on both the low-side and high-side power rails.
