MIC59P50 8-Bit Parallel-Input Protected Latched Driver General Description Features The MIC59P50 parallel-input latched driver is a highvoltage (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, undervoltage lockout (UVLO), and overcurrent shutdown. • • • • • • • • • • The bipolar/MOS combination provides an extremely lowpower latch with maximum interface flexibility. The MIC59P50 has open-collector outputs capable of sinking 500mA and integral diodes for inductive load transient suppression with a minimum output breakdown voltage rating of 80V above VEE (50V sustaining). The drivers can be operated with a split supply, where the negative supply is down to –20V and may be paralleled for higher load current capability. 4.4MHz minimum data input rate High-voltage, high-current outputs Per-output overcurrent shutdown (500mA typical) Undervoltage lockout Output fault flag Output transient protection diodes CMOS, PMOS, NMOS, and TTL-compatible inputs Internal pull-down resistors Low-power CMOS latches Single or split supply operation With a 5V logic supply, the MIC59P50 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 at 500mA. 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 2µs will not activate overcurrent 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 0.5V is provided. Datasheets and support documentation are available on Micrel’s website at: www.micrel.com.

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 and reset the FLAG. Overtemperature faults are not latched and require no reset pulse.
