MIC59P60 Micrel MIC59P60 8-Bit Serial-Input Protected Latched Driver General Description Features The MIC59P60 serial-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, CLOCK, SERIAL DATA INPUT, and OUTPUT ENABLE functions. Similar to the MIC5842, 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 MIC59P60 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 (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. 3.3 MHz Minimum Data-Input Rate Output Current Shutdown (500mA Typical) Under Voltage Lockout Thermal Shutdown Output Fault Flag CMOS, PMOS, NMOS, and TTL Compatible Internal Pull-Up/Pull-Down Resistors Low Power CMOS Logic and Latches High Voltage Current Sink Outputs Output Transient-Protection Diodes Single or Split Supply Operation Ordering Information Part Number Using a 5V logic supply, the MIC59P60 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. By using the serial data output, drivers may be cascaded for interface applications requiring additional drive lines. Temperature Range Package MIC59P60BN –40°C to +85°C 20-Pin Plastic DIP MIC59P60BV –40°C to +85°C 20-Pin PLCC MIC59P60BWM –40°C to +85°C 20-Pin Wide SOIC Each of these eight outputs has an independent over current shutdown of 500 mA. Upon over-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 current shutdown. Temperatures above 165°C will shut down the device and activate the error flag. The UVLO circuit prevents operation at low VDD; hysteresis of 0.5V is provided.

On succeeding CLOCK pulses, the registers shift data information towards the SERIAL DATA OUTPUT. The SERIAL DATA must appear at the input prior to the rising edge of the CLOCK input waveform. Holding CLEAR high results in a data logic "0" being clocked into the shift register, turning off respective channels. Information present at any register is transferred to its respective latch when the STROBE is high (serial-to-parallel conversion). The latches will continue to accept new data as long as the STROBE is held high. Applications where the latches are bypassed (STROBE tied high) will require that the ENABLE input be high to prevent invalid output states. When the ENABLE input is high, all of the output buffers are disabled (OFF) without affecting information stored in the latches or shift register. With the ENABLE input low, the outputs are controlled by the state of the latches. A positive OE/RESET pulse resets the FLAG and the output after a current shutdown fault. Over-temperature faults are not latched and require no reset pulse.
