| e5130 Low Voltage CMOS Driver Circuit Description The e5130 contains 4 independent driver outputs with an ON resistance of typ. 25 W (15 W) tor the P-channel output transistors and typ. 20 W (13 W) for the N-channel output transistors; at a supply voltage of 1.5 V (3 V). To obtain a fast transition of the outputs, even for slow rise/-fall time input signals, all digital inputs (IN1 ... IN4) have a schmitt-trigger characteristic; with a hysteresis of typ. 50 mV. If a higher driving capability is needed, all inputs and outputs may be connected in parallel. In this case the rise/-fall time of the input signals IN1 ... IN4 must be less than 200 nsec. Due to the fast switching characteristic of the tristatable output drivers, the circuit is also suited as low voltage bus driver. Features D 1.1 - 3.6 V operating voltage range D 4 non-inverting, tristatable drivers for the following applications: - Motor driver for bipolar stepper motors in watch/clock applications - Driver for piezoelectric transducers (buzzer) - LED Driver - Line driver for medium speed applications Advantages D High load current at low supply voltage D Replaces several discrete transistors D Tri-state operation possible D Possible applications: - Motor driver - Radio controlled clock/watch - Line driver for mini-computer, laptop - LED driver - Relay driver Pad Configuration OUT1 OUT2 OUT3 OUT4 VDD VSS VDD IN1 ...

A2, 13-Mar-01 1 (4) e5130 Absolute Maximum Ratings Absolute maximum ratings define parameter limits which, it exceeded, may permanently change or damage the device. All inputs and outputs on circuits are highly protected against electrostatic discharges. However, precautions to minimize build-up of electrostatic charges during handling are recommended. The circuits are protected against supply voltage reversal for typically 5 minutes, if the current is limited to 120 mA.
