Monolithic Digital IC
LA5657H
System Power Supply IC for Car AV Systems
Overview
The LA5657H provides 10 V/2.2 A and 5 V/1.4 A
external pnp transistor based low-saturation regulators
with standby functions, as well as 3.3 V, 5 V, and 8 V
constant voltage, open collector, and VCC linked (VCC -
1 V) outputs that can be controlled from serial data (CCB).
It also includes three reset detection circuits for the VDD,
ACC, and battery systems. The LA5657H is an optimal
power supply IC for car audio systems and similar
products.
Features
• Built-in 10 V and 5 V regulators (external pnp transistor
required) with standby (on/off) functions
• Extensive set of output systems: two 8 V systems, single
5 V, 3.25 V, and 5 to 9.7 V (set with an external resistor)
systems, four open-collector output systems, and two
VCC linked systems.
• Three reset circuits: ACC, VDD (with delay circuit), and
BATT
• Full complement of protection circuits
— Overcurrent protection circuits for all output systems
except the open collector and reset circuits
— Thermal protection circuits for all outputs except the
reset circuits
