Fonctionnalités et applications

The MIC59P50YWM parallel-input latched driver is a high-voltage (80 V), high-current (500 mA) integrated circuit comprised of eight CMOS data latches, a bipolar Darlington transistor driver for each latch, and CMOS control circuitry for the common CLEAR, STROBE, and OUTPUT ENABLE functions. Similar to the MIC5801, additional protection circuitry supplied on this device includes thermal shutdown, under voltage lockout (UVLO), and over-current shutdown. The bipolar/MOS combination provides an extremely low-power latch with maximum interface flexibility.

The MIC59P50 has open-collector outputs capable of sinking 500 mA and integral diodes for inductive load transient suppression with a minimum output breakdown voltage rating of 80 V above VEE (50 V sustaining). The CMOS inputs are compatible with standard CMOS, PMOS, and NMOS circuits. TTL circuits may require pull-up resistors. Each of these eight outputs has an independent over-current shutdown at 500 mA. Upon current shutdown, the affected channel will turn OFF and the flag will go low until VDD is cycled or the ENABLE/RESET pin is pulsed high. Current pulses less than 2 µs will not activate over-current shutdown. Temperatures above 165°C will shut down the device and activate the open collector FLAG output at pin 1. The UVLO circuit disables the outputs at low VDD; hysteresis of 0.5 V is provided.
