Features & Applications

The MIC58P01YV 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 overcurrent shutdown. The bipolar/CMOS combination provides an extremely low-power latch with maximum interface flexibility.

The MIC58P01 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 (50 V sustaining). The drivers may be paralleled for higher load current capability. With a 5 V logic supply, the MIC58P01 will typically operate at better than 5 MHz. With a 12 V logic supply, significantly higher speeds are obtained. 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 overcurrent shutdown of 500 mA. Upon current shutdown, the affected channel will turn OFF until VDD is cycled or the ENABLE/RESET pin is pulsed high. Current pulses less than 2 µs will not activate current shutdown. Temperatures above 165°C will shut down all outputs. The UVLO circuit disables the outputs at low VDD; hysteresis of 0.5V is provided.
