+ 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 4.4MHz Minimum Data Input Rate (80V), high-current (500mA) integrated circuit comprised of High-Voltage, High-Current Outputs eight CMOS data latches, a bipolar Darlington transistor Per-Output Overcurrent Shutdown (500mA typical) driver for each latch, and CMOS control circuitry for the Under Voltage Lockout common CLEAR, STROBE, and OUTPUT ENABLE functions. Thermal Shutdown Similar to the MIC5801, additional protection circuitry supplied Output Transient Protection Diodes on this device includes thermal shutdown, under voltage CMOS, PMOS, NMOS, and TTL Compatible Inputs lockout (UVLO), and overcurrent shutdown. Internal Pull-Down Resistors Low-Power CMOS Latches 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 80V (50V sustaining). The drivers may be paralleled for higher load current capability. With a 5V logic supply, the MIC58P01 will typically operate at Ordering Information better than 5MHz. With a 12V logic supply, significantly higher Part Number Temperature Range Package speeds are obtained. The CMOS inputs are compatible with standard CMOS, PMOS, and NMOS circuits. TTL circuits MIC58P01BN 40C to +85C 22-Pin Plastic DIP may require pull-up resistors. MIC58P01BV 40C to +85C 28-Pin PLCC Each of these eight outputs has an independent overcurrent MIC58P01BWM 40C to +85C 24-Pin Wide SOIC shutdown of 500mA. Upon current shutdown, the affected channel will turn OFF until V is cycled or the ENABLE/ DD RESET pin is pulsed high. Current pulses less than 2 s 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 provided.
