TC4432EJA

M Features • High Peak Output Current – 1.5A • Wide Input Supply Voltage Operating Range: - 4.5V to 30V • High Capacitive Load Drive Capability: - 1000 pF in 25 nsec • Short Delay Times – 300 mA Reverse Current • ESD Protected – 4 kV TC4431/TC4432 General Description The TC4431/TC4432 are 30V CMOS buffer/drivers suitable for use in high-side driver applications. They will not latch-up under any conditions within their power and voltage ratings. They can accept, without damage or logic upset, up to 300 mA of reverse current (of either polarity) being forced back into their outputs. All terminals are fully protected against up to 4 kV of electrostatic discharge. Undervoltage lockout circuitry forces the output to a ‘low’ state when the input supply voltage drops below 7V. For operation at lower voltages, disable the lockout and start-up circuit by grounding pin 3 (LOCK DIS ); for all other situations, pin 3 should be left floating. The under-voltage lockout and start-up circuit gives brownout protection when driving MOSFETS. 1.5A High-Speed 30V MOSFET Drivers Applications • Small Motor Drive • Power MOSFET Driver • Driving Bipolar Transistors Package Types 8-Pin PDIP/SOIC/CERDIP VDD 1 8 VDD IN 2 7 OUT TC4431 LOCK DIS 3 6 OUT GND 4 5 GND 2 7 Inverting 6 VDD 1 8 VDD IN 2 7 OUT TC4432 LOCK DIS 3 6 OUT GND 4 5 GND 2 7 6 Non Inverting  2003 Microchip Technology Inc.

The lockout pin enables/disables the undervoltage lock-out feature of the device. If undervoltage lockout is desired (output is not enabled until the bias voltage reaches 8.4V (typical) on the rising edge and is disabled when the bias voltage reaches 7.7V (typical) on the falling edge), the lockout pin should be left floating. If operation below 7V is desired, the lockout pin should be tied to ground. TABLE 3-1: Pin No. 1 2 3 4 5 6 7 8 PIN FUNCTION TABLE Description Supply Input, 4.5V to 30V TTL/CMOS Compatible Input Input Pin, Enable/Disable for UV Lockout Ground Ground Drive Output, Pull Down Drive Output, Pull Up Supply Input, 4.5V to 30V VDD IN Symbol LOCK DIS GND GND 3.4 Ground (GND) OUT OUT VDD The ground pins are the return path for the bias current and for the high peak currents which discharge the load capacitor. Both ground pins should be used to ensure proper operation. The ground pins should be tied into a ground plane or have short traces to the bias supply source return. 3.1 Supply Input (VDD) The V DD input is the bias supply input for the MOSFET driver and is rated for 4.5V to 30V with respect to the ground pins. The VDD input should be bypassed to ground with a local ceramic capacitor. The value of this capacitor should be chosen based on the capacitive load that is being driven. 3.5 Drive Output (OUT) 3.2 Control Input (IN) The TC4431/TC4432 devices have individual source and sink output pins. This feature can be used to adjust the rise and fall time independently by adding separate charge and discharge resistors external to the device. Pin 7 (source output) can source 3A peak currents into capacitive loads and pin 6 (sink output) can sink 1.5A peak currents from a capacitive load. The MOSFET driver input is a TTL/CMOS compatible input with 250 mV of hysteresis between the high and low threshold voltages. If an input signal level of greater than 12V is applied to the device, a series current limiting resistor is recommended.
