8-Bit Serial-Input Protected Latched Driver

General Description

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.

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.

Features

• 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

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 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 VDD; hysteresis of 0.5V is provided.

= 5V)

SERIAL DATA present at the input is transferred to the shift register on the logic “0” to logic “1” transition of the CLOCK input
pulse. 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.
