2 / 20 page UC1875-SP SLUSAQ9 – DECEMBER 2011 www.ti.com These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. DESCRIPTION (CONTINUED) Protective features include an undervoltage lockout which maintains all outputs in an active-low state until the supply reaches a 10.75 V threshold. 1.5 hysteresis is built in for reliable, boot-strapped chip supply. Overcurrent protection is provided, and will latch the outputs in the OFF state within 70 nsec of a fault. The current-fault circuitry implements full-cycle restart operation. Additional features include an error amplifier with bandwidth in excess of 7 MHz, a 5 V reference, provisions for soft-starting, and flexible ramp generation and slope compensation circuitry. This device is available in hermetically sealed cerdip, surface mount, and ceramic leadless chip carrier packages for –55°C to +125°C operation.
