(3)

Ω resistor con-

nected in series. Current is limited only by the 500

Ω re-

sistor.

(4)

Amplifiers 1 and 2

*1.2V) is recommended.

Unpredictable outputs may occur when the input is out-

side this range.

(5)

Hysteresis amplifier

*1.2V) is recommended.

Unpredictable outputs may occur when the input is out-

side this range.

(6)

Thermal shutdown circuit

The thermal shutdown circuit puts the driver outputs (8,

6, 5, 3 pin) to the open state at the temperature of 175

_C

(typical). The circuit is deactivated when the temperature

drops to about 155

_C.

(7)

Signal ground pin

Pins 1 and 24 are signal ground pins. Be noted that un-

predictable outputs may occur if your application causes

a large current between pins 1 and 24 via the bonding

wire IC chip.
