Product specification
TDA3608Q; TDA3608TH
FEATURES
General
• Two VP-state controlled regulators (regulator 1 and regulator 3) and a power switch
• Regulator 2 and reset circuit operate during load dump and thermal shutdown
• Separate control pins for switching regulator 1, regulator 3 and power switch
• Supply voltage range from −18 to +50 V • Low reverse current of regulator 2 • Low quiescent current (when regulator 1, regulator 3
and power switch are switched off) • Hold output circuit for regulator 1 (only valid when
regulator 3 output voltage >1.
