MIC58P01 8-Bit Parallel-Input Protected Latched Driver General Description Features The MIC58P01 parallel-input latched driver is a high- 4.4MHz Minimum Data Input Rate voltage (80V), high-current (500mA) integrated circuit High-Voltage, High-Current Outputs comprised of eight CMOS data latches, a bipolar Per-Output Overcurrent Shutdown (500mA typical) Darlington transistor driver for each latch, and CMOS Under Voltage Lockout control circuitry for the common CLEAR, STROBE, and OUTPUT ENABLE functions. Similar to the MIC5801, Thermal Shutdown additional protection circuitry supplied on this device Output Transient Protection Diodes includes thermal shutdown, under voltage lockout (UVLO), CMOS, PMOS, NMOS, and TTL Compatible Inputs and overcurrent shutdown. Internal Pull-Down Resistors The bipolar/CMOS combination provides an extremely Low-Power CMOS Latches 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 80V (50V sustaining). The drivers may be paralleled for higher load current capability. With a 5V logic supply, the MIC58P01 will typically operate at better than 5MHz. With a 12V 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 500mA. Upon current shutdown, the affected channel will turn OFF until V is cycled or the DD ENABLE/RESET pin is pulsed high. Current pulses less than 2s will not activate current shutdown. Temperatures above 165C will shut down all outputs. The UVLO circuit disables the outputs at low V hysteresis of 0.5V is DD provided.
