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
V
CC
linked systems.
Three reset circuits: A
CC
, V
DD
(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

(1) V
DD
reset block (
*
1)
The reset detection function detects the level of V
DD
5V input to V
DD
IN.
This reset function operates correctly when the V
DD
IN voltage is over 0.5 V, but is undefined when V
DD
IN is under 0.5 V. The reset voltage must never
exceed V
DD
IN.
The allowable range for the threshold voltage has a tolerance of 4.7%.
(2) BAT and ACC reset blocks (
*
2)
These reset detection outputs must operate correctly when the V
DD
IN voltage is over 2 V. The reset voltages must never exceed V
DD
IN.
The ACC detection function has no region where detection is unpredictable according to the value of the voltage detected. That is, the low level will be
detected correctly when ACC IN is 0 V.
The allowable range for the threshold voltage has a tolerance of 3.2%.
