e5130 Low Voltage CMOS Driver Circuit Description The e5130 contains 4 independent driver outputs with an ON resistance of typ. 25 (15 ) tor the P-channel output transistors and typ. 20 (13 ) 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 Advantages 1.1 – 3.6 V operating voltage range High load current at low supply voltage 4 non-inverting, tristatable drivers for the following applications: Replaces several discrete transistors – Motor driver for bipolar stepper motors in watch/clock applications Possible applications: Tri-state operation possible – Driver for piezoelectric transducers (buzzer) – Motor driver – Radio controlled clock/watch – LED Driver – Line driver for mini-computer, laptop – Line driver for medium speed applications – LED driver – Relay driver Pad Configuration OUT1 OUT2 OUT3 OUT4 Name VDD e5130 94 8178 TRI IN1 IN2 IN3 IN4 Description VDD Positive supply voltage VSS Negative supply voltage IN1 ...

A2, 13-Mar-01 Package Die Remarks Die in Trays 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.
