MIC59P60 Micrel MIC59P60 8-Bit Serial-Input Protected Latched Driver 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 and may be paralleled for higher load current capability. 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. 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 V 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 V hysteresis of 0.5V is provided. • 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 Temperature Range Package MIC59P60BN to +85°C 20-Pin Plastic DIP MIC59P60BV to +85°C 20-Pin PLCC MIC59P60BWM to +85°C 20-Pin Wide SOIC Functional Diagram CLOCK 3 SERIAL DATA IN 8-BIT SHIFT REGISTER Pin Configuration DIP and SOIC 20 FLAG 7 SERIAL DATA OUT 6 VDD CLEAR THERMAL SHUTDOWN I LIMIT VEE CLOCK SHIFT REGISTER LATCHES VSS 5 CLEAR 1 UVLO LATCHES MOS BIPOLAR 8 STROBE SERIAL DATA IN 4 9 OUTPUT ENABLE/RESET VSS 5 VDD 6 SERIAL DATA OUT 7 THERMAL SHUTDOWN ILIMIT SUB 2 K OUT 1 OUT 2 OUT 3 OUT 4 OUT 5 OUT 6 OUT 7 OUT 8 STROBE 8 OUTPUT 9 ENABLE/RESET VEE 10 SUB

MIC59P60
8-Bit Serial-Input Protected Latched Driver

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 and may be paralleled for higher load current capability.

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.

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 V
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 V hysteresis of 0.5V is provided.
