... Cf/PWM IN ANALOG GND SA60U www.cirrus.com DESCRIPTION The SA60 is a pulse width modulation amplifier that can supply 10A continuous current to the load. The full bridge amplifier can be operated over a wide range of supply voltages. All of the drive/control circuitry for the lowside and highside switches are internal to the hybrid. The PWM circuitry is internal as well, leaving ...

... ANALOG INPUT - is an analog input for controlling the PWM pulse width of the bridge. A voltage higher than Vcc/2 will produce greater than 50% duty cycle pulses out of B OUT. A voltage lower than Vcc/2 will produce greater than 50% duty cycle pulses out of A OUT. If using in the digital mode, bias this point at 1/2 the logic high level. DISABLE - Is the connection for disabling all 4 output switches. DISABLE high overrides all other inputs. When taken low, everything functions normally. An internal pullup to Vcc will keep DISABLE high if pin left open ‡ ‡ ISENSE B A OUT B OUT +Vs 12-pin Power SIP PACKAGE STYLE DP Formed Leads Available See package style EE 11 LOAD 9 SA60 SA60U ...

... Do not run small signal traces between the pins of the output section (pins 8-12). CURRENT SENSE There are two load current sensing pins, I SENSE A and I SENSE B. The two pins can be shorted to POWER GND in the voltage mode connection but both must be used in the current mode connection recommended that R SENSE resistors be non-inductive. Load current flows in the I SENSE pins. The SA60 has no internal current limit. TRANSIENT SUPPRESSION An RC network of a 100 pF Capacitor and a one ohm resistor is required as shown in the external connection dia- gram on page 1. This network assures proper operation under various loads. Minimal power is dissipated in the resistor. ...
