MIC58P01 Micrel MIC58P01 8-Bit Parallel-Input Protected Latched Driver Final Information General Description Features The MIC58P01 parallel-input latched driver is a high-voltage (80V), high-current (500mA) 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 lowpower 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. 4.4MHz Minimum Data Input Rate High-Voltage, High-Current Outputs Per-Output Overcurrent Shutdown (500mA typical) Under Voltage Lockout Thermal Shutdown Output Transient Protection Diodes CMOS, PMOS, NMOS, and TTL Compatible Inputs Internal Pull-Down Resistors Low-Power CMOS Latches Ordering Information Part Number Each of these eight outputs has an independent overcurrent shutdown of 500mA. 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 2s will not activate current shutdown. Temperatures above 165C will shut down all outputs. The UVLO circuit disables the outputs at low VDD; hysteresis of 0.5V is provided.

Truth Table Output Information present at an input is transferred to its latch when the STROBE is high. A high CLEAR input will set all latches to the output OFF condition regardless of the Data or STROBE input levels. A high OUTPUT ENABLE will set all outputs to the OFF condition, regardless of any other input conditions. When the OUTPUT ENABLE is low, the outputs depend on the state of their respective latches. If current shutdown is activated, the OUTPUT ENABLE must be pulsed high to restore operation. Over temperature faults are not latched and require no reset pulse.
